Given numbers are 705, 209, 703, 278

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 209 are 11 x 19

Prime factors of 703 are 19 x 37

Prime factors of 278 are 2 x 139

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

Given numbers are 705, 209, 703, 278

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

Apply this formula for all numbers.

Step1:

LCM(705, 209) = 147345

GCD(705, 209) = ( 705 x 209 ) / 147345

= 705 / 209

= 705

Step2:

LCM(1, 703) = 703

GCD(1, 703) = ( 1 x 703 ) / 703

= 1 / 703

= 1

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 705, 209, 703, 278 is 1
