Given numbers are 421, 790, 630, 290

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 790 are 2 x 5 x 79

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

Prime factors of 290 are 2 x 5 x 29

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

Given numbers are 421, 790, 630, 290

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

Apply this formula for all numbers.

Step1:

LCM(421, 790) = 332590

GCD(421, 790) = ( 421 x 790 ) / 332590

= 421 / 790

= 421

Step2:

LCM(1, 630) = 630

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

= 1 / 630

= 1

Step3:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 421, 790, 630, 290 is 1
