Given numbers are 411, 630, 390, 745

The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 745 are 5 x 149

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

Given numbers are 411, 630, 390, 745

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

Apply this formula for all numbers.

Step1:

LCM(411, 630) = 86310

GCD(411, 630) = ( 411 x 630 ) / 86310

= 411 / 630

= 411

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 745) = 2235

GCD(3, 745) = ( 3 x 745 ) / 2235

= 3 / 745

= 3

So, Greatest Common Divisor of 411, 630, 390, 745 is 1
