Given numbers are 30, 64, 31, 71
The list of prime factors of all numbers are
Prime factors of 30 are 2 x 3 x 5
Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 31 are 31
Prime factors of 71 are 71
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 30, 64, 31, 71 using LCM Formula
Given numbers are 30, 64, 31, 71
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(30, 64) = 960
GCD(30, 64) = ( 30 x 64 ) / 960
= 30 / 64
= 30
Step2:
LCM(2, 31) = 62
GCD(2, 31) = ( 2 x 31 ) / 62
= 2 / 31
= 2
Step3:
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
= 1 / 71
= 1
So, Greatest Common Divisor of 30, 64, 31, 71 is 1
