Given numbers are 658, 663, 140, 505

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 663 are 3 x 13 x 17

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 505 are 5 x 101

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

Given numbers are 658, 663, 140, 505

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

Apply this formula for all numbers.

Step1:

LCM(658, 663) = 436254

GCD(658, 663) = ( 658 x 663 ) / 436254

= 658 / 663

= 658

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 658, 663, 140, 505 is 1
