1. Get the source numerical values

Numerator is 3334

Denominator is 12

the source fraction is 3334 12
2. Calculate the greatest common divisor (GCD) using the Euclidean algorithm
1)
let 3334 is a, 12 is b, then:
3334 / 12 = 277 ...... 10
remainder is 10, not eq 0, so go on...

2)
let 12 is a, 10 is b, then:
12 / 10 = 1 ...... 2
remainder is 2, not eq 0, so go on...

3)
let 10 is a, 2 is b, then:
10 / 2 = 5 ...... 0
remainder is 0, eq 0, the Greatest Common Divisor (GCD) of 3334 and 12 is 2


3. Finally

Found GCD of 3334 and 12 is 2

3334 12 = 3334 12 = 1667 6
