Given numbers are 862, 414, 988, 640

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

Apply this formula for all numbers.

Step1:

LCM(862, 414) = 178434

GCD(862, 414) = ( 862 x 414 ) / 178434

= 862 / 414

= 862

Step2:

LCM(2, 988) = 988

GCD(2, 988) = ( 2 x 988 ) / 988

= 2 / 988

= 2

Step3:

LCM(2, 640) = 640

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

= 2 / 640

= 2

So, Greatest Common Divisor of 862, 414, 988, 640 is 2
