Given numbers are 124, 980, 91, 791

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

Apply this formula for all numbers.

Step1:

LCM(124, 980) = 30380

GCD(124, 980) = ( 124 x 980 ) / 30380

= 124 / 980

= 124

Step2:

LCM(4, 91) = 364

GCD(4, 91) = ( 4 x 91 ) / 364

= 4 / 91

= 4

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 124, 980, 91, 791 is 1
