Given numbers are 623, 780, 450, 331

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 331 are 331

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

Given numbers are 623, 780, 450, 331

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

Apply this formula for all numbers.

Step1:

LCM(623, 780) = 485940

GCD(623, 780) = ( 623 x 780 ) / 485940

= 623 / 780

= 623

Step2:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

Step3:

LCM(1, 331) = 331

GCD(1, 331) = ( 1 x 331 ) / 331

= 1 / 331

= 1

So, Greatest Common Divisor of 623, 780, 450, 331 is 1
