Given numbers are 690, 517, 80, 663

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 517 are 11 x 47

Prime factors of 80 are 2 x 2 x 2 x 2 x 5

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 690, 517, 80, 663

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

Apply this formula for all numbers.

Step1:

LCM(690, 517) = 356730

GCD(690, 517) = ( 690 x 517 ) / 356730

= 690 / 517

= 690

Step2:

LCM(1, 80) = 80

GCD(1, 80) = ( 1 x 80 ) / 80

= 1 / 80

= 1

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 690, 517, 80, 663 is 1
