Steps to Calculate GCD of 628, 478, 645, 157 using LCM Formula
Given numbers are 628, 478, 645, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 478) = 150092
GCD(628, 478) = ( 628 x 478 ) / 150092
= 628 / 478
= 628
Step2:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 628, 478, 645, 157 is 1
