Given numbers are 225, 300, 161, 778

The list of prime factors of all numbers are

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 161 are 7 x 23

Prime factors of 778 are 2 x 389

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

Given numbers are 225, 300, 161, 778

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

Apply this formula for all numbers.

Step1:

LCM(225, 300) = 900

GCD(225, 300) = ( 225 x 300 ) / 900

= 225 / 300

= 225

Step2:

LCM(75, 161) = 12075

GCD(75, 161) = ( 75 x 161 ) / 12075

= 75 / 161

= 75

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 225, 300, 161, 778 is 1
