Given numbers are 957, 580, 639, 812

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

Apply this formula for all numbers.

Step1:

LCM(957, 580) = 19140

GCD(957, 580) = ( 957 x 580 ) / 19140

= 957 / 580

= 957

Step2:

LCM(29, 639) = 18531

GCD(29, 639) = ( 29 x 639 ) / 18531

= 29 / 639

= 29

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 957, 580, 639, 812 is 1
