Given numbers are 214, 156, 640, 651

The list of prime factors of all numbers are

Prime factors of 214 are 2 x 107

Prime factors of 156 are 2 x 2 x 3 x 13

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

Prime factors of 651 are 3 x 7 x 31

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

Given numbers are 214, 156, 640, 651

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

Apply this formula for all numbers.

Step1:

LCM(214, 156) = 16692

GCD(214, 156) = ( 214 x 156 ) / 16692

= 214 / 156

= 214

Step2:

LCM(2, 640) = 640

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

= 2 / 640

= 2

Step3:

LCM(2, 651) = 1302

GCD(2, 651) = ( 2 x 651 ) / 1302

= 2 / 651

= 2

So, Greatest Common Divisor of 214, 156, 640, 651 is 1
