Given numbers are 820, 710, 656

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

Apply this formula for all numbers.

Step1:

LCM(820, 710) = 58220

GCD(820, 710) = ( 820 x 710 ) / 58220

= 820 / 710

= 820

Step2:

LCM(10, 656) = 3280

GCD(10, 656) = ( 10 x 656 ) / 3280

= 10 / 656

= 10

So, Greatest Common Divisor of 820, 710, 656 is 2
