Given numbers are 640, 836, 427, 988

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 427 are 7 x 61

Prime factors of 988 are 2 x 2 x 13 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 640, 836, 427, 988

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

Apply this formula for all numbers.

Step1:

LCM(640, 836) = 133760

GCD(640, 836) = ( 640 x 836 ) / 133760

= 640 / 836

= 640

Step2:

LCM(4, 427) = 1708

GCD(4, 427) = ( 4 x 427 ) / 1708

= 4 / 427

= 4

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 640, 836, 427, 988 is 1
