Given numbers are 903, 644, 945, 997

The list of prime factors of all numbers are

Prime factors of 903 are 3 x 7 x 43

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 997 are 997

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

Given numbers are 903, 644, 945, 997

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

Apply this formula for all numbers.

Step1:

LCM(903, 644) = 83076

GCD(903, 644) = ( 903 x 644 ) / 83076

= 903 / 644

= 903

Step2:

LCM(7, 945) = 945

GCD(7, 945) = ( 7 x 945 ) / 945

= 7 / 945

= 7

Step3:

LCM(7, 997) = 6979

GCD(7, 997) = ( 7 x 997 ) / 6979

= 7 / 997

= 7

So, Greatest Common Divisor of 903, 644, 945, 997 is 1
