Steps to Calculate GCD of 658, 561, 347, 268 using LCM Formula
Given numbers are 658, 561, 347, 268
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 561) = 369138
GCD(658, 561) = ( 658 x 561 ) / 369138
= 658 / 561
= 658
Step2:
LCM(1, 347) = 347
GCD(1, 347) = ( 1 x 347 ) / 347
= 1 / 347
= 1
Step3:
LCM(1, 268) = 268
GCD(1, 268) = ( 1 x 268 ) / 268
= 1 / 268
= 1
So, Greatest Common Divisor of 658, 561, 347, 268 is 1
