Given numbers are 186, 951, 489, 638

The list of prime factors of all numbers are

Prime factors of 186 are 2 x 3 x 31

Prime factors of 951 are 3 x 317

Prime factors of 489 are 3 x 163

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 186, 951, 489, 638

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

Apply this formula for all numbers.

Step1:

LCM(186, 951) = 58962

GCD(186, 951) = ( 186 x 951 ) / 58962

= 186 / 951

= 186

Step2:

LCM(3, 489) = 489

GCD(3, 489) = ( 3 x 489 ) / 489

= 3 / 489

= 3

Step3:

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

= 3 / 638

= 3

So, Greatest Common Divisor of 186, 951, 489, 638 is 1
