Given numbers are 381, 547, 420, 910

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 547 are 547

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 910 are 2 x 5 x 7 x 13

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

Given numbers are 381, 547, 420, 910

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

Apply this formula for all numbers.

Step1:

LCM(381, 547) = 208407

GCD(381, 547) = ( 381 x 547 ) / 208407

= 381 / 547

= 381

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

So, Greatest Common Divisor of 381, 547, 420, 910 is 1
