Steps to Calculate GCD of 771, 416, 689, 423 using LCM Formula

Given numbers are 771, 416, 689, 423

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

Apply this formula for all numbers.

Step1:

LCM(771, 416) = 320736

GCD(771, 416) = ( 771 x 416 ) / 320736

= 771 / 416

= 771


Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1


Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1
