Steps to Calculate GCD of 836, 647, 665, 157 using LCM Formula
Given numbers are 836, 647, 665, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(836, 647) = 540892
GCD(836, 647) = ( 836 x 647 ) / 540892
= 836 / 647
= 836
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 836, 647, 665, 157 is 1
