Given numbers are 427, 390, 102, 387

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 102 are 2 x 3 x 17

Prime factors of 387 are 3 x 3 x 43

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

Given numbers are 427, 390, 102, 387

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

Apply this formula for all numbers.

Step1:

LCM(427, 390) = 166530

GCD(427, 390) = ( 427 x 390 ) / 166530

= 427 / 390

= 427

Step2:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 427, 390, 102, 387 is 1
