Given numbers are 705, 309, 910, 880

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 309 are 3 x 103

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

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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

Given numbers are 705, 309, 910, 880

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

Apply this formula for all numbers.

Step1:

LCM(705, 309) = 72615

GCD(705, 309) = ( 705 x 309 ) / 72615

= 705 / 309

= 705

Step2:

LCM(3, 910) = 2730

GCD(3, 910) = ( 3 x 910 ) / 2730

= 3 / 910

= 3

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 705, 309, 910, 880 is 1
