Given numbers are 842, 945, 351, 378

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 351 are 3 x 3 x 3 x 13

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

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

Given numbers are 842, 945, 351, 378

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

Apply this formula for all numbers.

Step1:

LCM(842, 945) = 795690

GCD(842, 945) = ( 842 x 945 ) / 795690

= 842 / 945

= 842

Step2:

LCM(1, 351) = 351

GCD(1, 351) = ( 1 x 351 ) / 351

= 1 / 351

= 1

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 842, 945, 351, 378 is 1
