Steps to Calculate GCD of 668, 265, 144, 638 using LCM Formula

Given numbers are 668, 265, 144, 638

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(668, 265) = 177020

GCD(668, 265) = ( 668 x 265 ) / 177020

= 668 / 265

= 668


Step2:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1


Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1


So, Greatest Common Divisor of 668, 265, 144, 638 is 1
