Given numbers are 828, 646, 160, 778

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

Apply this formula for all numbers.

Step1:

LCM(828, 646) = 267444

GCD(828, 646) = ( 828 x 646 ) / 267444

= 828 / 646

= 828

Step2:

LCM(2, 160) = 160

GCD(2, 160) = ( 2 x 160 ) / 160

= 2 / 160

= 2

Step3:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

So, Greatest Common Divisor of 828, 646, 160, 778 is 2
