Steps to Calculate GCD of 642, 557, 69, 265 using LCM Formula
Given numbers are 642, 557, 69, 265
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 557) = 357594
GCD(642, 557) = ( 642 x 557 ) / 357594
= 642 / 557
= 642
Step2:
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
= 1 / 69
= 1
Step3:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
So, Greatest Common Divisor of 642, 557, 69, 265 is 1
