Given numbers are 753, 390, 605, 210

The list of prime factors of all numbers are

Prime factors of 753 are 3 x 251

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

Prime factors of 605 are 5 x 11 x 11

Prime factors of 210 are 2 x 3 x 5 x 7

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

Given numbers are 753, 390, 605, 210

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

Apply this formula for all numbers.

Step1:

LCM(753, 390) = 97890

GCD(753, 390) = ( 753 x 390 ) / 97890

= 753 / 390

= 753

Step2:

LCM(3, 605) = 1815

GCD(3, 605) = ( 3 x 605 ) / 1815

= 3 / 605

= 3

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 753, 390, 605, 210 is 1
