Given numbers are 38, 71, 98, 18

The list of prime factors of all numbers are

Prime factors of 38 are 2 x 19

Prime factors of 71 are 71

Prime factors of 98 are 2 x 7 x 7

Prime factors of 18 are 2 x 3 x 3

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

Given numbers are 38, 71, 98, 18

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

Apply this formula for all numbers.

Step1:

LCM(38, 71) = 2698

GCD(38, 71) = ( 38 x 71 ) / 2698

= 38 / 71

= 38

Step2:

LCM(1, 98) = 98

GCD(1, 98) = ( 1 x 98 ) / 98

= 1 / 98

= 1

Step3:

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

= 1 / 18

= 1

So, Greatest Common Divisor of 38, 71, 98, 18 is 1
