Given numbers are 612, 802, 581, 645

The list of prime factors of all numbers are

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

Prime factors of 802 are 2 x 401

Prime factors of 581 are 7 x 83

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 612, 802, 581, 645

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

Apply this formula for all numbers.

Step1:

LCM(612, 802) = 245412

GCD(612, 802) = ( 612 x 802 ) / 245412

= 612 / 802

= 612

Step2:

LCM(2, 581) = 1162

GCD(2, 581) = ( 2 x 581 ) / 1162

= 2 / 581

= 2

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 612, 802, 581, 645 is 1
