Given numbers are 658, 665, 471, 520

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 665 are 5 x 7 x 19

Prime factors of 471 are 3 x 157

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 658, 665, 471, 520

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

Apply this formula for all numbers.

Step1:

LCM(658, 665) = 62510

GCD(658, 665) = ( 658 x 665 ) / 62510

= 658 / 665

= 658

Step2:

LCM(7, 471) = 3297

GCD(7, 471) = ( 7 x 471 ) / 3297

= 7 / 471

= 7

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 658, 665, 471, 520 is 1
