Given numbers are 640, 884, 812, 196

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

Apply this formula for all numbers.

Step1:

LCM(640, 884) = 141440

GCD(640, 884) = ( 640 x 884 ) / 141440

= 640 / 884

= 640

Step2:

LCM(4, 812) = 812

GCD(4, 812) = ( 4 x 812 ) / 812

= 4 / 812

= 4

Step3:

LCM(4, 196) = 196

GCD(4, 196) = ( 4 x 196 ) / 196

= 4 / 196

= 4

So, Greatest Common Divisor of 640, 884, 812, 196 is 4
