Given numbers are 209, 885, 158, 630

The list of prime factors of all numbers are

Prime factors of 209 are 11 x 19

Prime factors of 885 are 3 x 5 x 59

Prime factors of 158 are 2 x 79

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 209, 885, 158, 630

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

Apply this formula for all numbers.

Step1:

LCM(209, 885) = 184965

GCD(209, 885) = ( 209 x 885 ) / 184965

= 209 / 885

= 209

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 209, 885, 158, 630 is 1
