Given numbers are 442, 642, 839, 551

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 642 are 2 x 3 x 107

Prime factors of 839 are 839

Prime factors of 551 are 19 x 29

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

Given numbers are 442, 642, 839, 551

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

Apply this formula for all numbers.

Step1:

LCM(442, 642) = 141882

GCD(442, 642) = ( 442 x 642 ) / 141882

= 442 / 642

= 442

Step2:

LCM(2, 839) = 1678

GCD(2, 839) = ( 2 x 839 ) / 1678

= 2 / 839

= 2

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 442, 642, 839, 551 is 1
