Given numbers are 778, 515, 856

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

Apply this formula for all numbers.

Step1:

LCM(778, 515) = 400670

GCD(778, 515) = ( 778 x 515 ) / 400670

= 778 / 515

= 778

Step2:

LCM(1, 856) = 856

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

= 1 / 856

= 1

So, Greatest Common Divisor of 778, 515, 856 is 1
