Given numbers are 640, 784, 868, 962

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

Apply this formula for all numbers.

Step1:

LCM(640, 784) = 31360

GCD(640, 784) = ( 640 x 784 ) / 31360

= 640 / 784

= 640

Step2:

LCM(16, 868) = 3472

GCD(16, 868) = ( 16 x 868 ) / 3472

= 16 / 868

= 16

Step3:

LCM(4, 962) = 1924

GCD(4, 962) = ( 4 x 962 ) / 1924

= 4 / 962

= 4

So, Greatest Common Divisor of 640, 784, 868, 962 is 2
