Given numbers are 631,45,153

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 631,45,153 is 482715.

Find LCM of 631,45,153 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 3 x 631 x 5 x 17 = 482715

Therefore, the lowest common multiple of 631,45,153 is 482715.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

631 x 45 x 153 = 4344435

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

631 : 1, 631

45 : 1, 3, 5, 9, 15, 45

153 : 1, 3, 9, 17, 51, 153

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,45,153, is 1.

Now, the common factors can be found like this.

631:631

45:3x 3x 5

153:3x 3x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 4344435/(1x9)

LCM = 4344435/9

LCM = 482715

Thus, we can understand that the LCM of 631,45,153 is 482715.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 748, 80, 980
• LCM of 329, 98, 732
