Steps to Calculate GCD of 957, 245, 957, 639 using LCM Formula
Given numbers are 957, 245, 957, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(957, 245) = 234465
GCD(957, 245) = ( 957 x 245 ) / 234465
= 957 / 245
= 957
Step2:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 957, 245, 957, 639 is 1
