Given numbers are 636, 256, 505, 989

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

Apply this formula for all numbers.

Step1:

LCM(636, 256) = 40704

GCD(636, 256) = ( 636 x 256 ) / 40704

= 636 / 256

= 636

Step2:

LCM(4, 505) = 2020

GCD(4, 505) = ( 4 x 505 ) / 2020

= 4 / 505

= 4

Step3:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

So, Greatest Common Divisor of 636, 256, 505, 989 is 1
