Given numbers are 756, 427, 821, 129

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

Apply this formula for all numbers.

Step1:

LCM(756, 427) = 46116

GCD(756, 427) = ( 756 x 427 ) / 46116

= 756 / 427

= 756

Step2:

LCM(7, 821) = 5747

GCD(7, 821) = ( 7 x 821 ) / 5747

= 7 / 821

= 7

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 756, 427, 821, 129 is 1
