Given numbers are 680, 747, 856

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

Apply this formula for all numbers.

Step1:

LCM(680, 747) = 507960

GCD(680, 747) = ( 680 x 747 ) / 507960

= 680 / 747

= 680

Step2:

LCM(1, 856) = 856

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

= 1 / 856

= 1

So, Greatest Common Divisor of 680, 747, 856 is 1
