Given numbers are 725, 665, 142, 129

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

Apply this formula for all numbers.

Step1:

LCM(725, 665) = 96425

GCD(725, 665) = ( 725 x 665 ) / 96425

= 725 / 665

= 725

Step2:

LCM(5, 142) = 710

GCD(5, 142) = ( 5 x 142 ) / 710

= 5 / 142

= 5

Step3:

LCM(1, 129) = 129

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

= 1 / 129

= 1

So, Greatest Common Divisor of 725, 665, 142, 129 is 1
