Given numbers are 645, 572, 160, 248

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 248 are 2 x 2 x 2 x 31

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

Given numbers are 645, 572, 160, 248

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

Apply this formula for all numbers.

Step1:

LCM(645, 572) = 368940

GCD(645, 572) = ( 645 x 572 ) / 368940

= 645 / 572

= 645

Step2:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 645, 572, 160, 248 is 1
