Steps to Calculate GCD of 787, 551, 302, 531 using LCM Formula

Given numbers are 787, 551, 302, 531

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

Apply this formula for all numbers.

Step1:

LCM(787, 551) = 433637

GCD(787, 551) = ( 787 x 551 ) / 433637

= 787 / 551

= 787


Step2:

LCM(1, 302) = 302

GCD(1, 302) = ( 1 x 302 ) / 302

= 1 / 302

= 1


Step3:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1
