Given numbers are 855, 822, 100, 193

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 822 are 2 x 3 x 137

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 193 are 193

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

Given numbers are 855, 822, 100, 193

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

Apply this formula for all numbers.

Step1:

LCM(855, 822) = 234270

GCD(855, 822) = ( 855 x 822 ) / 234270

= 855 / 822

= 855

Step2:

LCM(3, 100) = 300

GCD(3, 100) = ( 3 x 100 ) / 300

= 3 / 100

= 3

Step3:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

So, Greatest Common Divisor of 855, 822, 100, 193 is 1
