Given numbers are 124, 820, 291

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

Apply this formula for all numbers.

Step1:

LCM(124, 820) = 25420

GCD(124, 820) = ( 124 x 820 ) / 25420

= 124 / 820

= 124

Step2:

LCM(4, 291) = 1164

GCD(4, 291) = ( 4 x 291 ) / 1164

= 4 / 291

= 4

So, Greatest Common Divisor of 124, 820, 291 is 1
