Given numbers are 640, 724, 163, 810

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 724 are 2 x 2 x 181

Prime factors of 163 are 163

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 640, 724, 163, 810

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

Apply this formula for all numbers.

Step1:

LCM(640, 724) = 115840

GCD(640, 724) = ( 640 x 724 ) / 115840

= 640 / 724

= 640

Step2:

LCM(4, 163) = 652

GCD(4, 163) = ( 4 x 163 ) / 652

= 4 / 163

= 4

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 640, 724, 163, 810 is 1
