Given numbers are 612, 522, 105, 821

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 522 are 2 x 3 x 3 x 29

Prime factors of 105 are 3 x 5 x 7

Prime factors of 821 are 821

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

Given numbers are 612, 522, 105, 821

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

Apply this formula for all numbers.

Step1:

LCM(612, 522) = 17748

GCD(612, 522) = ( 612 x 522 ) / 17748

= 612 / 522

= 612

Step2:

LCM(18, 105) = 630

GCD(18, 105) = ( 18 x 105 ) / 630

= 18 / 105

= 18

Step3:

LCM(3, 821) = 2463

GCD(3, 821) = ( 3 x 821 ) / 2463

= 3 / 821

= 3

So, Greatest Common Divisor of 612, 522, 105, 821 is 1
