Given numbers are 488, 721, 390, 754

The list of prime factors of all numbers are

Prime factors of 488 are 2 x 2 x 2 x 61

Prime factors of 721 are 7 x 103

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

Prime factors of 754 are 2 x 13 x 29

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

Given numbers are 488, 721, 390, 754

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

Apply this formula for all numbers.

Step1:

LCM(488, 721) = 351848

GCD(488, 721) = ( 488 x 721 ) / 351848

= 488 / 721

= 488

Step2:

LCM(1, 390) = 390

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

= 1 / 390

= 1

Step3:

LCM(1, 754) = 754

GCD(1, 754) = ( 1 x 754 ) / 754

= 1 / 754

= 1

So, Greatest Common Divisor of 488, 721, 390, 754 is 1
