Given numbers are 390, 547, 146, 681

The list of prime factors of all numbers are

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

Prime factors of 547 are 547

Prime factors of 146 are 2 x 73

Prime factors of 681 are 3 x 227

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

Given numbers are 390, 547, 146, 681

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

Apply this formula for all numbers.

Step1:

LCM(390, 547) = 213330

GCD(390, 547) = ( 390 x 547 ) / 213330

= 390 / 547

= 390

Step2:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 390, 547, 146, 681 is 1
