Given numbers are 640, 944, 636, 777

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

Apply this formula for all numbers.

Step1:

LCM(640, 944) = 37760

GCD(640, 944) = ( 640 x 944 ) / 37760

= 640 / 944

= 640

Step2:

LCM(16, 636) = 2544

GCD(16, 636) = ( 16 x 636 ) / 2544

= 16 / 636

= 16

Step3:

LCM(4, 777) = 3108

GCD(4, 777) = ( 4 x 777 ) / 3108

= 4 / 777

= 4

So, Greatest Common Divisor of 640, 944, 636, 777 is 1
