### GCF of 25 and 30 by Listing common Factors

Factors that 25: 1, 5, 25Factors that 30: 1, 2, 3, 5, 6, 10, 15, 30

There room 2 usual factors that 25 and 30, that are 1 and 5. Therefore, the greatest common factor of 25 and also 30 is 5.

### GCF that 25 and 30 by element Factorization

Prime administer of 25 and 30 is (5 × 5) and (2 × 3 × 5) respectively. Together visible, 25 and 30 have only one common prime element i.e. 5. Hence, the GCF that 25 and also 30 is 5.

### GCF that 25 and also 30 by long Division

GCF that 25 and 30 is the divisor that we acquire when the remainder i do not care 0 after doing long division repeatedly.

Step 2: since the remainder ≠ 0, we will certainly divide the divisor of step 1 (25) through the remainder (5).Step 3: Repeat this procedure until the remainder = 0.

The corresponding divisor (5) is the GCF of 25 and also 30.

## GCF of 25 and also 30 Examples

Example 1: For 2 numbers, GCF = 5 and LCM = 150. If one number is 30, uncover the various other number.

Solution:

Given: GCF (y, 30) = 5 and LCM (y, 30) = 150∵ GCF × LCM = 30 × (y)⇒ y = (GCF × LCM)/30⇒ y = (5 × 150)/30⇒ y = 25Therefore, the other number is 25.

Example 2: uncover the best number that divides 25 and 30 exactly.

Solution:

The greatest number that divides 25 and also 30 exactly is their greatest typical factor, i.e. GCF of 25 and 30.⇒ components of 25 and also 30:

Factors that 25 = 1, 5, 25Factors that 30 = 1, 2, 3, 5, 6, 10, 15, 30

Therefore, the GCF of 25 and also 30 is 5.

Example 3: uncover the GCF of 25 and also 30, if their LCM is 150.

Solution:

∵ LCM × GCF = 25 × 30⇒ GCF(25, 30) = (25 × 30)/150 = 5Therefore, the greatest common factor that 25 and also 30 is 5.
