Given numbers are 190, 855, 658, 630

The list of prime factors of all numbers are

Prime factors of 190 are 2 x 5 x 19

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 658 are 2 x 7 x 47

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 190, 855, 658, 630

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

Apply this formula for all numbers.

Step1:

LCM(190, 855) = 1710

GCD(190, 855) = ( 190 x 855 ) / 1710

= 190 / 855

= 190

Step2:

LCM(95, 658) = 62510

GCD(95, 658) = ( 95 x 658 ) / 62510

= 95 / 658

= 95

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 190, 855, 658, 630 is 1
