Given numbers are 407, 645, 911, 612

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 911 are 911

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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

Given numbers are 407, 645, 911, 612

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

Apply this formula for all numbers.

Step1:

LCM(407, 645) = 262515

GCD(407, 645) = ( 407 x 645 ) / 262515

= 407 / 645

= 407

Step2:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

Step3:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

So, Greatest Common Divisor of 407, 645, 911, 612 is 1
