Given numbers are 408, 424, 133, 840

The list of prime factors of all numbers are

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

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 133 are 7 x 19

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 408, 424, 133, 840

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

Apply this formula for all numbers.

Step1:

LCM(408, 424) = 21624

GCD(408, 424) = ( 408 x 424 ) / 21624

= 408 / 424

= 408

Step2:

LCM(8, 133) = 1064

GCD(8, 133) = ( 8 x 133 ) / 1064

= 8 / 133

= 8

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 408, 424, 133, 840 is 1
