Given numbers are 644, 264, 316, 140

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

Apply this formula for all numbers.

Step1:

LCM(644, 264) = 42504

GCD(644, 264) = ( 644 x 264 ) / 42504

= 644 / 264

= 644

Step2:

LCM(4, 316) = 316

GCD(4, 316) = ( 4 x 316 ) / 316

= 4 / 316

= 4

Step3:

LCM(4, 140) = 140

GCD(4, 140) = ( 4 x 140 ) / 140

= 4 / 140

= 4

So, Greatest Common Divisor of 644, 264, 316, 140 is 4
