Given numbers are 125, 291, 21, 939

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

Apply this formula for all numbers.

Step1:

LCM(125, 291) = 36375

GCD(125, 291) = ( 125 x 291 ) / 36375

= 125 / 291

= 125

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 125, 291, 21, 939 is 1
