Given numbers are 791, 656, 856

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

Apply this formula for all numbers.

Step1:

LCM(791, 656) = 518896

GCD(791, 656) = ( 791 x 656 ) / 518896

= 791 / 656

= 791

Step2:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 791, 656, 856 is 1
