Given numbers are 561, 462, 65, 694

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 65 are 5 x 13

Prime factors of 694 are 2 x 347

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

Given numbers are 561, 462, 65, 694

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

Apply this formula for all numbers.

Step1:

LCM(561, 462) = 7854

GCD(561, 462) = ( 561 x 462 ) / 7854

= 561 / 462

= 561

Step2:

LCM(33, 65) = 2145

GCD(33, 65) = ( 33 x 65 ) / 2145

= 33 / 65

= 33

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 561, 462, 65, 694 is 1
