GCD of numbers is the greatest common divisor

So, the GCD (420, 614, 33, 644) = 1.

Given numbers are 420, 614, 33, 644

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 614 are 2 x 307

Prime factors of 33 are 3 x 11

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

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

Given numbers are 420, 614, 33, 644

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

Apply this formula for all numbers.

Step1:

LCM(420, 614) = 128940

GCD(420, 614) = ( 420 x 614 ) / 128940

= 420 / 614

= 420

Step2:

LCM(2, 33) = 66

GCD(2, 33) = ( 2 x 33 ) / 66

= 2 / 33

= 2

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 420, 614, 33, 644 is 1
