Given numbers are 254, 102, 820

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

Apply this formula for all numbers.

Step1:

LCM(254, 102) = 12954

GCD(254, 102) = ( 254 x 102 ) / 12954

= 254 / 102

= 254

Step2:

LCM(2, 820) = 820

GCD(2, 820) = ( 2 x 820 ) / 820

= 2 / 820

= 2

So, Greatest Common Divisor of 254, 102, 820 is 2
