## GCF of 28 and 70 Examples

**Example 1: For two numbers, GCF = 14 and LCM = 140. If one number is 28, find the various other number.**

**Solution:**

Given: GCF (y, 28) = 14 and LCM (y, 28) = 140∵ GCF × LCM = 28 × (y)⇒ y = (GCF × LCM)/28⇒ y = (14 × 140)/28⇒ y = 70Therefore, the other number is 70.

**Example 2: uncover the GCF the 28 and 70, if your LCM is 140. **

**Solution: **

∵ LCM × GCF = 28 × 70⇒ GCF(28, 70) = (28 × 70)/140 = 14Therefore, the greatest common factor the 28 and also 70 is 14.

**Example 3: The product of two numbers is 1960. If their GCF is 14, what is your LCM? **

**Solution:**

Given: GCF = 14 and also product of numbers = 1960∵ LCM × GCF = product that numbers⇒ LCM = Product/GCF = 1960/14Therefore, the LCM is 140.
