Given numbers are 725, 790, 821

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

Apply this formula for all numbers.

Step1:

LCM(725, 790) = 114550

GCD(725, 790) = ( 725 x 790 ) / 114550

= 725 / 790

= 725

Step2:

LCM(5, 821) = 4105

GCD(5, 821) = ( 5 x 821 ) / 4105

= 5 / 821

= 5

So, Greatest Common Divisor of 725, 790, 821 is 1
