GCF of two or more numbers Calculator allows you to quickly calculate the GCF of 1, 4, 8 i.e. 1 largest integer that divides all the numbers equally.

Greatest common factor (GCF) of 1, 4, 8 is **1**.

GCF(1, 4, 8) = 1

Greatest common factor or Greatest common divisor (GCD) can be calculated in two ways

- Greatest Common Factor of 1, 4, 8 by common division method
- Greatest Common Factor of 1, 4, 8 with matching the biggest common factor

∴ GCF of numbers is 1 because of no common factors present between them.

**Factors of 1**
