Steps to Calculate GCD of 649, 197, 355, 977 using LCM Formula
Given numbers are 649, 197, 355, 977
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 197) = 127853
GCD(649, 197) = ( 649 x 197 ) / 127853
= 649 / 197
= 649
Step2:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
Step3:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
So, Greatest Common Divisor of 649, 197, 355, 977 is 1
