Given numbers are 920, 646, 820

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

Apply this formula for all numbers.

Step1:

LCM(920, 646) = 297160

GCD(920, 646) = ( 920 x 646 ) / 297160

= 920 / 646

= 920

Step2:

LCM(2, 820) = 820

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

= 2 / 820

= 2

So, Greatest Common Divisor of 920, 646, 820 is 2
