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

Apply this formula for all numbers.

Step1:

LCM(858, 124) = 53196

GCD(858, 124) = ( 858 x 124 ) / 53196

= 858 / 124

= 858

Step2:

LCM(2, 520) = 520

GCD(2, 520) = ( 2 x 520 ) / 520

= 2 / 520

= 2

So, Greatest Common Divisor of 858, 124, 520 is 2
