What is the G.C.F of 2 and 3?
- 1
- 2
- 3
- 4
Hint:
1. The highest/ greatest factor that is common among 2 or more numbers is known as Greatest Common Factor.
2. To find GCF of 2 or more numbers, we first factorize all the given numbers and then find common factors among the 2 numbers. Then these common factors are multiplied to find the HCF.
The correct answer is: 1
Solution-
Step-1: Factorise the given numbers i.e. 2 & 3-
Factors of 2- 2 * 1
Factors of 3- 3 * 1
Step-2: Find all common factors- 1
Step-3: Multiply all the common factors the maximum number of times they occur-
= 1
Hence, 1 is the HCF of 2 & 3.
Final Answer- 'Option a' i.e. 1.
