Steps to Calculate GCD of 638, 471, 69, 370 using LCM Formula

Given numbers are 638, 471, 69, 370

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

Apply this formula for all numbers.

Step1:

LCM(638, 471) = 300498

GCD(638, 471) = ( 638 x 471 ) / 300498

= 638 / 471

= 638


Step2:

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

= 1 / 69

= 1


Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1
