Given numbers are 778, 830, 408

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

Apply this formula for all numbers.

Step1:

LCM(778, 830) = 322870

GCD(778, 830) = ( 778 x 830 ) / 322870

= 778 / 830

= 778

Step2:

LCM(2, 408) = 408

GCD(2, 408) = ( 2 x 408 ) / 408

= 2 / 408

= 2

So, Greatest Common Divisor of 778, 830, 408 is 2
