The greatest common factor (GCF) of two numbers is the largest number that divides both numbers evenly. To find the GCF of 135 and 171, we need to identify the common factors of both numbers. The prime factorization of 135 is 3 x 3 x 3 x 5, and the prime factorization of 171 is 3 x 3 x 19. The common factors are 3 x 3 = 9, so the greatest common factor of 135 and 171 is 9.
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
The GCF of 63, 171, and 306 is 9.
171/60 = 57/20 by dividing the numerator and the denominator by 3 which is their greatest common factor
To find the least common multiple you first need to identify the prime factors of the two numbers. In this case: 99 = 3x3x11 121 = 11x11 The next step is to identify any common factors and discard the duplicate. In this case, both numbers have 11 as a common factor, so we can discard one, leaving us with 3, 3, 11 and 11. Multiply these together to find the LCM: 3x3x11x11=1,089 Thus the least common multiple of 99 and 121 is 1,089
There cannot be a common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
The greatest common factor of 171 and 475 is 19.
It is 19
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
