What is the greatest common factor of 60 and 72? - Socratic
网页2017年1月3日 · 12 I like to answer these questions by first doing prime factorizations: 60=2xx30=2xx2xx15=2xx2xx3xx5 72=2xx36=2xx2xx18=2xx2xx2xx9=2xx2xx2xx3xx3 The GCF will have all the numbers that are common to both 60 and 72. GCF=? Let's start with 2's first. 60 has two 2s, while 72 has three. Two 2s are common to both, so our GCF will have two 2s: GCF=2xx2xx? Now 3s. 60 has one 3 and 72 has two 3s. One 3 ...

What is the GCF of 36 and 60? - Socratic
网页2016年3月31日 · A method of finding GCF and LCM - especially of several numbers if they are larger than usual - is to write the numbers as the product of the prime factors. In this way we can immediately see which factors are common: × × × 36 = 2 ×2 ×3 × 3. × × × 60 = 2 ×2 ×3 × x × 5. GCF = × = 2 × 2 × 3 × × x = 12. LCM = × = 2 ×2 ×3 ×3 ...

How do you find the greatest common factor of - Socratic
网页2016年12月8日 · There are two 2s that both terms have - and nothing else in common. So the GCF is 2 × 2 = 4. 4 To find the GCF, let's see what these two terms are made of: 60y=2xx30y=2xx2xx15y=2xx2xx3xx5xxy 56x^2=2xx28x^2=2xx2xx14x^2=2xx2xx2xx7xx x^2 So what is the biggest number we can make that is within both of the terms we're looking at? There are two 2s ...
How do you find the greatest common factor of 56, 63?
网页The GCF of 56 and 63 is 7 One way to find the greatest common factor (GCF) of two positive numbers goes as follows: Divide the larger number by the smaller to give a quotient and remainder. If the remainder is 0 then the smaller number is the GCF. Otherwise repeat with the smaller number and the remainder. In our example: 63 / 56 = 1" " with remainder 7 56 / 7 = 8" " with remainder 0 So the ...
What is the greatest common factor of 54 and 36? - Socratic
网页2016年4月5日 · That will tell you everything you need to know about a number. Look for all the common factors: 36 = 2 × 2 ×3 ×3. 54 = 2 × 3 × 3 × 3 −−−−−−−−−−−−−−−−−−−−. H CF = 2 ×3 ×3 = 18.

What is the greatest common factor for 12 and 15? | Socratic
网页2016年4月10日 · 1 Answer. The GCF of 12 and 15 is 3. One way to find this is to break down these two numbers into their prime factorisations: 12 = 2 × 2 × 3. 15 = 3 × 5. We see that the only common factor (greater than 1) is 3, so that is the greatest common factor. If the two numbers had more than one prime factor in common, you would multiply them ...
