Given numbers are 166, 640, 224, 651

The list of prime factors of all numbers are

Prime factors of 166 are 2 x 83

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

Prime factors of 224 are 2 x 2 x 2 x 2 x 2 x 7

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 166, 640, 224, 651

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

Apply this formula for all numbers.

Step1:

LCM(166, 640) = 53120

GCD(166, 640) = ( 166 x 640 ) / 53120

= 166 / 640

= 166

Step2:

LCM(2, 224) = 224

GCD(2, 224) = ( 2 x 224 ) / 224

= 2 / 224

= 2

Step3:

LCM(2, 651) = 1302

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

= 2 / 651

= 2

So, Greatest Common Divisor of 166, 640, 224, 651 is 1
