Make use of GCD Calculator to determine the Greatest Common Divisor of 628, 645, 102 i.e. 1 largest integer that divides all the numbers equally.
GCD of 628, 645, 102 is 1
GCD(628, 645, 102) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 628, 645, 102 is 1
GCD(628, 645, 102) = 1
Given Input numbers are 628, 645, 102
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 5, 15, 43, 129, 215, 645
Divisors of 102
List of positive integer divisors of 102 that divides 102 without a remainder.
1, 2, 3, 6, 17, 34, 51, 102
Greatest Common Divisior
We found the divisors of 628, 645, 102 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 628, 645, 102 is 1.
Therefore, GCD of numbers 628, 645, 102 is 1
Given Input Data is 628, 645, 102
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 628 is 2 x 2 x 157
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 102 is 2 x 3 x 17
The above numbers do not have any common prime factor. So GCD is 1
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(628, 645) = 405060
GCD(628, 645) = ( 628 x 645 ) / 405060
GCD(628, 645) = 405060 / 405060
GCD(628, 645) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 102
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
GCD(1, 102) = 102 / 102
GCD(1, 102) = 1
GCD of 628, 645, 102 is 1
