Steps to Calculate GCD of 157, 870, 634, 644 using LCM Formula
Given numbers are 157, 870, 634, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 870) = 136590
GCD(157, 870) = ( 157 x 870 ) / 136590
= 157 / 870
= 157
Step2:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 157, 870, 634, 644 is 1
