Given numbers are 460, 645, 890, 393

The list of prime factors of all numbers are

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 645 are 3 x 5 x 43

Prime factors of 890 are 2 x 5 x 89

Prime factors of 393 are 3 x 131

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

Given numbers are 460, 645, 890, 393

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

Apply this formula for all numbers.

Step1:

LCM(460, 645) = 59340

GCD(460, 645) = ( 460 x 645 ) / 59340

= 460 / 645

= 460

Step2:

LCM(5, 890) = 890

GCD(5, 890) = ( 5 x 890 ) / 890

= 5 / 890

= 5

Step3:

LCM(5, 393) = 1965

GCD(5, 393) = ( 5 x 393 ) / 1965

= 5 / 393

= 5

So, Greatest Common Divisor of 460, 645, 890, 393 is 1
