Given numbers are 409, 630, 492, 638

The list of prime factors of all numbers are

Prime factors of 409 are 409

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

Prime factors of 492 are 2 x 2 x 3 x 41

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 409, 630, 492, 638

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

Apply this formula for all numbers.

Step1:

LCM(409, 630) = 257670

GCD(409, 630) = ( 409 x 630 ) / 257670

= 409 / 630

= 409

Step2:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 409, 630, 492, 638 is 1
