Given numbers are 660, 450, 434, 805

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Prime factors of 434 are 2 x 7 x 31

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 660, 450, 434, 805

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

Apply this formula for all numbers.

Step1:

LCM(660, 450) = 9900

GCD(660, 450) = ( 660 x 450 ) / 9900

= 660 / 450

= 660

Step2:

LCM(30, 434) = 6510

GCD(30, 434) = ( 30 x 434 ) / 6510

= 30 / 434

= 30

Step3:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

So, Greatest Common Divisor of 660, 450, 434, 805 is 1
