Given numbers are 521, 783, 605, 450

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 605 are 5 x 11 x 11

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

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

Given numbers are 521, 783, 605, 450

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

Apply this formula for all numbers.

Step1:

LCM(521, 783) = 407943

GCD(521, 783) = ( 521 x 783 ) / 407943

= 521 / 783

= 521

Step2:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

Step3:

LCM(1, 450) = 450

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

= 1 / 450

= 1

So, Greatest Common Divisor of 521, 783, 605, 450 is 1
