Given numbers are 456, 316, 640, 440

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

Apply this formula for all numbers.

Step1:

LCM(456, 316) = 36024

GCD(456, 316) = ( 456 x 316 ) / 36024

= 456 / 316

= 456

Step2:

LCM(4, 640) = 640

GCD(4, 640) = ( 4 x 640 ) / 640

= 4 / 640

= 4

Step3:

LCM(4, 440) = 440

GCD(4, 440) = ( 4 x 440 ) / 440

= 4 / 440

= 4

So, Greatest Common Divisor of 456, 316, 640, 440 is 4
