Given numbers are 210, 305, 446, 775

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 305 are 5 x 61

Prime factors of 446 are 2 x 223

Prime factors of 775 are 5 x 5 x 31

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

Given numbers are 210, 305, 446, 775

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

Apply this formula for all numbers.

Step1:

LCM(210, 305) = 12810

GCD(210, 305) = ( 210 x 305 ) / 12810

= 210 / 305

= 210

Step2:

LCM(5, 446) = 2230

GCD(5, 446) = ( 5 x 446 ) / 2230

= 5 / 446

= 5

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 210, 305, 446, 775 is 1
