Given numbers are 430, 360, 644, 665

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

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

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 430, 360, 644, 665

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

Apply this formula for all numbers.

Step1:

LCM(430, 360) = 15480

GCD(430, 360) = ( 430 x 360 ) / 15480

= 430 / 360

= 430

Step2:

LCM(10, 644) = 3220

GCD(10, 644) = ( 10 x 644 ) / 3220

= 10 / 644

= 10

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 430, 360, 644, 665 is 1
