It’s the math question please help

GCF: 5

LCM: 30

Please mark BRAINLIEST! Thanks!

GCF of 10 & 15 = 5

LCM of 10 & 15 = 30

Explanation:

To find the greatest common factors of both numbers, use a factor tree and determine which is the greatest factor they have in common. Let's start by creating a factor tree for ten.

10 = 2 × 5

So, since two and five are the only factors of ten and are both prime numbers, they are the prime factors of ten.

Now, let's create a factor tree for fifteen.

15 = 3 × 5

So, since three and five are the only factors of fifteen and both are prime numbers, they are the prime factors of fifteen.

Finally, list both factors side by side and determine which is the greatest factor they have in common.

Factors of 10 = 2, 5

Factors of 15 = 3, 5

Therefore, five is the greatest common factor of ten and fifteen.

Next, we'll find the least common multiple of ten and fifteen by listing their multiples and determining which is the least multiple they have in common.

Write a list of the multiples of ten and fifteen:

Multiples of 10 = 10, 20, 30...

Multiples of 15 = 15, 30...

Therefore, thirty is the least common multiple of ten and fifteen.
