Given numbers are 378, 387, 870, 442

The list of prime factors of all numbers are

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 387 are 3 x 3 x 43

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 378, 387, 870, 442

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

Apply this formula for all numbers.

Step1:

LCM(378, 387) = 16254

GCD(378, 387) = ( 378 x 387 ) / 16254

= 378 / 387

= 378

Step2:

LCM(9, 870) = 2610

GCD(9, 870) = ( 9 x 870 ) / 2610

= 9 / 870

= 9

Step3:

LCM(3, 442) = 1326

GCD(3, 442) = ( 3 x 442 ) / 1326

= 3 / 442

= 3

So, Greatest Common Divisor of 378, 387, 870, 442 is 1
