Given numbers are 474, 686, 247, 143

The list of prime factors of all numbers are

Prime factors of 474 are 2 x 3 x 79

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

Prime factors of 247 are 13 x 19

Prime factors of 143 are 11 x 13

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

Given numbers are 474, 686, 247, 143

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

Apply this formula for all numbers.

Step1:

LCM(474, 686) = 162582

GCD(474, 686) = ( 474 x 686 ) / 162582

= 474 / 686

= 474

Step2:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

Step3:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

So, Greatest Common Divisor of 474, 686, 247, 143 is 1
