Given numbers are 175, 125, 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(175, 125) = 875

GCD(175, 125) = ( 175 x 125 ) / 875

= 175 / 125

= 175

Step2:

LCM(25, 790) = 3950

GCD(25, 790) = ( 25 x 790 ) / 3950

= 25 / 790

= 25

Step3:

LCM(5, 821) = 4105

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

= 5 / 821

= 5

So, Greatest Common Divisor of 175, 125, 790, 821 is 1
