Given numbers are 215, 378, 930, 298

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

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

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 298 are 2 x 149

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

Given numbers are 215, 378, 930, 298

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

Apply this formula for all numbers.

Step1:

LCM(215, 378) = 81270

GCD(215, 378) = ( 215 x 378 ) / 81270

= 215 / 378

= 215

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1

So, Greatest Common Divisor of 215, 378, 930, 298 is 1
