Steps to Calculate GCD of 405, 288, 947, 634 using LCM Formula

Given numbers are 405, 288, 947, 634

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

Apply this formula for all numbers.

Step1:

LCM(405, 288) = 12960

GCD(405, 288) = ( 405 x 288 ) / 12960

= 405 / 288

= 405


Step2:

LCM(9, 947) = 8523

GCD(9, 947) = ( 9 x 947 ) / 8523

= 9 / 947

= 9


Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1


So, Greatest Common Divisor of 405, 288, 947, 634 is 1
