Given numbers are 419, 654, 408, 120

The list of prime factors of all numbers are

Prime factors of 419 are 419

Prime factors of 654 are 2 x 3 x 109

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 419, 654, 408, 120

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

Apply this formula for all numbers.

Step1:

LCM(419, 654) = 274026

GCD(419, 654) = ( 419 x 654 ) / 274026

= 419 / 654

= 419

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 419, 654, 408, 120 is 1
