Given numbers are 730, 638, 473, 138

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 638 are 2 x 11 x 29

Prime factors of 473 are 11 x 43

Prime factors of 138 are 2 x 3 x 23

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

Given numbers are 730, 638, 473, 138

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

Apply this formula for all numbers.

Step1:

LCM(730, 638) = 232870

GCD(730, 638) = ( 730 x 638 ) / 232870

= 730 / 638

= 730

Step2:

LCM(2, 473) = 946

GCD(2, 473) = ( 2 x 473 ) / 946

= 2 / 473

= 2

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 730, 638, 473, 138 is 1
