Given numbers are 360, 747, 247, 390

The list of prime factors of all numbers are

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 747 are 3 x 3 x 83

Prime factors of 247 are 13 x 19

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

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

Given numbers are 360, 747, 247, 390

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

Apply this formula for all numbers.

Step1:

LCM(360, 747) = 29880

GCD(360, 747) = ( 360 x 747 ) / 29880

= 360 / 747

= 360

Step2:

LCM(9, 247) = 2223

GCD(9, 247) = ( 9 x 247 ) / 2223

= 9 / 247

= 9

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 360, 747, 247, 390 is 1
