Given numbers are 134, 816, 644, 421

The list of prime factors of all numbers are

Prime factors of 134 are 2 x 67

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

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

Prime factors of 421 are 421

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

Given numbers are 134, 816, 644, 421

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

Apply this formula for all numbers.

Step1:

LCM(134, 816) = 54672

GCD(134, 816) = ( 134 x 816 ) / 54672

= 134 / 816

= 134

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 421) = 842

GCD(2, 421) = ( 2 x 421 ) / 842

= 2 / 421

= 2

So, Greatest Common Divisor of 134, 816, 644, 421 is 1
