GCD of numbers is the greatest common divisor

So, the GCD (434, 644, 85, 816) = 1.

Given numbers are 434, 644, 85, 816

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

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

Prime factors of 85 are 5 x 17

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 434, 644, 85, 816

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

Apply this formula for all numbers.

Step1:

LCM(434, 644) = 19964

GCD(434, 644) = ( 434 x 644 ) / 19964

= 434 / 644

= 434

Step2:

LCM(14, 85) = 1190

GCD(14, 85) = ( 14 x 85 ) / 1190

= 14 / 85

= 14

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 434, 644, 85, 816 is 1
