Given numbers are 645, 900, 181, 497

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 181 are 181

Prime factors of 497 are 7 x 71

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

Given numbers are 645, 900, 181, 497

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

Apply this formula for all numbers.

Step1:

LCM(645, 900) = 38700

GCD(645, 900) = ( 645 x 900 ) / 38700

= 645 / 900

= 645

Step2:

LCM(15, 181) = 2715

GCD(15, 181) = ( 15 x 181 ) / 2715

= 15 / 181

= 15

Step3:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

So, Greatest Common Divisor of 645, 900, 181, 497 is 1
