Given numbers are 120, 625, 124, 991

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

Apply this formula for all numbers.

Step1:

LCM(120, 625) = 15000

GCD(120, 625) = ( 120 x 625 ) / 15000

= 120 / 625

= 120

Step2:

LCM(5, 124) = 620

GCD(5, 124) = ( 5 x 124 ) / 620

= 5 / 124

= 5

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 120, 625, 124, 991 is 1
