Answer: 4
Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.
Method:
One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
The factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108.
The factors of 172 are 1, 2, 4, 43, 86, and 172.
The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.
The greatest common factor of 630 , 172 = 2
The Least Common Multiple (LCM) for 108 172 is 4,644.
Since 107 is a prime number, its only factors are 1 and 107. Since 107 is not a factor of 168, that leaves 1 as the greatest common factor.
You need at least two numbers to find a greatest COMMONFactor.The greatest COMMON factor for 171 will depend upon the other number(s) with which it has COMMON factors, but it WILL be one of the factors of 171, namely one of: 1, 3, 9, 19, 57, 171
182/2=9191/7=13182=2*7*13238/2=119119/7=17238=2*7*172*7*132*7*172*7=14=GCF
Yes, 55 over 172 can be simplified. The greatest common divisor (GCD) of 55 and 172 is 1, so there are no common factors to simplify further. Therefore, 55 over 172 is already in simplified form.
The GCF is: 4
No.
Yes.
Use a factor tree. 172 86, 2 43,2,2
2 AND 43
LCM(172, 48) = 2064.
