Given numbers are 442, 510, 556, 640

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

Apply this formula for all numbers.

Step1:

LCM(442, 510) = 6630

GCD(442, 510) = ( 442 x 510 ) / 6630

= 442 / 510

= 442

Step2:

LCM(34, 556) = 9452

GCD(34, 556) = ( 34 x 556 ) / 9452

= 34 / 556

= 34

Step3:

LCM(2, 640) = 640

GCD(2, 640) = ( 2 x 640 ) / 640

= 2 / 640

= 2

So, Greatest Common Divisor of 442, 510, 556, 640 is 2
