Given numbers are 644, 136, 637, 316

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

Apply this formula for all numbers.

Step1:

LCM(644, 136) = 21896

GCD(644, 136) = ( 644 x 136 ) / 21896

= 644 / 136

= 644

Step2:

LCM(4, 637) = 2548

GCD(4, 637) = ( 4 x 637 ) / 2548

= 4 / 637

= 4

Step3:

LCM(1, 316) = 316

GCD(1, 316) = ( 1 x 316 ) / 316

= 1 / 316

= 1

So, Greatest Common Divisor of 644, 136, 637, 316 is 1
