Steps to Calculate GCD of 649, 395, 155, 557 using LCM Formula
Given numbers are 649, 395, 155, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 395) = 256355
GCD(649, 395) = ( 649 x 395 ) / 256355
= 649 / 395
= 649
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 649, 395, 155, 557 is 1
