Given numbers are 105, 217, 778, 205

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 217 are 7 x 31

Prime factors of 778 are 2 x 389

Prime factors of 205 are 5 x 41

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

Given numbers are 105, 217, 778, 205

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

Apply this formula for all numbers.

Step1:

LCM(105, 217) = 3255

GCD(105, 217) = ( 105 x 217 ) / 3255

= 105 / 217

= 105

Step2:

LCM(7, 778) = 5446

GCD(7, 778) = ( 7 x 778 ) / 5446

= 7 / 778

= 7

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 105, 217, 778, 205 is 1
