Given numbers are 921, 344, 945, 878

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 344 are 2 x 2 x 2 x 43

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

Prime factors of 878 are 2 x 439

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

Given numbers are 921, 344, 945, 878

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

Apply this formula for all numbers.

Step1:

LCM(921, 344) = 316824

GCD(921, 344) = ( 921 x 344 ) / 316824

= 921 / 344

= 921

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 921, 344, 945, 878 is 1
