Given numbers are 657, 471, 568, 143

The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

Prime factors of 471 are 3 x 157

Prime factors of 568 are 2 x 2 x 2 x 71

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 657, 471, 568, 143

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

Apply this formula for all numbers.

Step1:

LCM(657, 471) = 103149

GCD(657, 471) = ( 657 x 471 ) / 103149

= 657 / 471

= 657

Step2:

LCM(3, 568) = 1704

GCD(3, 568) = ( 3 x 568 ) / 1704

= 3 / 568

= 3

Step3:

LCM(1, 143) = 143

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

= 1 / 143

= 1

So, Greatest Common Divisor of 657, 471, 568, 143 is 1
