Given numbers are 621, 228, 490, 344

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 344 are 2 x 2 x 2 x 43

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

Given numbers are 621, 228, 490, 344

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

Apply this formula for all numbers.

Step1:

LCM(621, 228) = 47196

GCD(621, 228) = ( 621 x 228 ) / 47196

= 621 / 228

= 621

Step2:

LCM(3, 490) = 1470

GCD(3, 490) = ( 3 x 490 ) / 1470

= 3 / 490

= 3

Step3:

LCM(1, 344) = 344

GCD(1, 344) = ( 1 x 344 ) / 344

= 1 / 344

= 1

So, Greatest Common Divisor of 621, 228, 490, 344 is 1
