Given numbers are 977, 808, 646, 902

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

Apply this formula for all numbers.

Step1:

LCM(977, 808) = 789416

GCD(977, 808) = ( 977 x 808 ) / 789416

= 977 / 808

= 977

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

So, Greatest Common Divisor of 977, 808, 646, 902 is 1
