Given numbers are 675, 455, 682, 690

The list of prime factors of all numbers are

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 455 are 5 x 7 x 13

Prime factors of 682 are 2 x 11 x 31

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

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

Given numbers are 675, 455, 682, 690

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

Apply this formula for all numbers.

Step1:

LCM(675, 455) = 61425

GCD(675, 455) = ( 675 x 455 ) / 61425

= 675 / 455

= 675

Step2:

LCM(5, 682) = 3410

GCD(5, 682) = ( 5 x 682 ) / 3410

= 5 / 682

= 5

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 675, 455, 682, 690 is 1
