Given numbers are 645, 295, 753, 520

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 295 are 5 x 59

Prime factors of 753 are 3 x 251

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 645, 295, 753, 520

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

Apply this formula for all numbers.

Step1:

LCM(645, 295) = 38055

GCD(645, 295) = ( 645 x 295 ) / 38055

= 645 / 295

= 645

Step2:

LCM(5, 753) = 3765

GCD(5, 753) = ( 5 x 753 ) / 3765

= 5 / 753

= 5

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 645, 295, 753, 520 is 1
