Given numbers are 413, 645, 252, 688

The list of prime factors of all numbers are

Prime factors of 413 are 7 x 59

Prime factors of 645 are 3 x 5 x 43

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 413, 645, 252, 688

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

Apply this formula for all numbers.

Step1:

LCM(413, 645) = 266385

GCD(413, 645) = ( 413 x 645 ) / 266385

= 413 / 645

= 413

Step2:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 413, 645, 252, 688 is 1
