Given numbers are 705, 980, 258, 443

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 258 are 2 x 3 x 43

Prime factors of 443 are 443

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

Given numbers are 705, 980, 258, 443

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

Apply this formula for all numbers.

Step1:

LCM(705, 980) = 138180

GCD(705, 980) = ( 705 x 980 ) / 138180

= 705 / 980

= 705

Step2:

LCM(5, 258) = 1290

GCD(5, 258) = ( 5 x 258 ) / 1290

= 5 / 258

= 5

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 705, 980, 258, 443 is 1
