Given numbers are 690, 416, 663, 851

The list of prime factors of all numbers are

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

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 663 are 3 x 13 x 17

Prime factors of 851 are 23 x 37

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

Given numbers are 690, 416, 663, 851

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

Apply this formula for all numbers.

Step1:

LCM(690, 416) = 143520

GCD(690, 416) = ( 690 x 416 ) / 143520

= 690 / 416

= 690

Step2:

LCM(2, 663) = 1326

GCD(2, 663) = ( 2 x 663 ) / 1326

= 2 / 663

= 2

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 690, 416, 663, 851 is 1
