Given numbers are 686, 756, 154, 603

The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 154 are 2 x 7 x 11

Prime factors of 603 are 3 x 3 x 67

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

Given numbers are 686, 756, 154, 603

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

Apply this formula for all numbers.

Step1:

LCM(686, 756) = 37044

GCD(686, 756) = ( 686 x 756 ) / 37044

= 686 / 756

= 686

Step2:

LCM(14, 154) = 154

GCD(14, 154) = ( 14 x 154 ) / 154

= 14 / 154

= 14

Step3:

LCM(14, 603) = 8442

GCD(14, 603) = ( 14 x 603 ) / 8442

= 14 / 603

= 14

So, Greatest Common Divisor of 686, 756, 154, 603 is 1
