Steps to Calculate GCD of 987, 691, 161, 938 using LCM Formula

Given numbers are 987, 691, 161, 938

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

Apply this formula for all numbers.

Step1:

LCM(987, 691) = 682017

GCD(987, 691) = ( 987 x 691 ) / 682017

= 987 / 691

= 987


Step2:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1


Step3:

LCM(1, 938) = 938

GCD(1, 938) = ( 1 x 938 ) / 938

= 1 / 938

= 1
