Given numbers are 403, 648, 190, 974

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 190 are 2 x 5 x 19

Prime factors of 974 are 2 x 487

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

Given numbers are 403, 648, 190, 974

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

Apply this formula for all numbers.

Step1:

LCM(403, 648) = 261144

GCD(403, 648) = ( 403 x 648 ) / 261144

= 403 / 648

= 403

Step2:

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

= 1 / 190

= 1

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 403, 648, 190, 974 is 1
