Given numbers are 781, 450, 570, 906

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

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

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 906 are 2 x 3 x 151

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

Given numbers are 781, 450, 570, 906

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

Apply this formula for all numbers.

Step1:

LCM(781, 450) = 351450

GCD(781, 450) = ( 781 x 450 ) / 351450

= 781 / 450

= 781

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 781, 450, 570, 906 is 1
