Calculate the LCM of 450,867,918

Given numbers are 450,867,918

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

The LCM of 450,867,918 is 390150.

Find LCM of 450,867,918 with Prime Factorization


2 450, 867, 918
3 225, 867, 459
3 75, 289, 153
17 25, 289, 51
25, 17, 3

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

2 x 3 x 3 x 17 x 25 x 17 x 3 = 390150

Therefore, the lowest common multiple of 450,867,918 is 390150.

LCM Formula to Find Lowest Common Multiple of 450,867,918

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.

450 x 867 x 918 = 358157700

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.

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

867 : 1, 3, 17, 51, 289, 867

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,867,918, is 3.

Now, the common factors can be found like this.

450:2x 3x 3x 5x 5

867:3x 17x 17

918:2x 3x 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.

2x 3x 3x 17 = 306

Therefore, the value for common factors is 306.

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 = 358157700/(3x306)

LCM = 358157700/918

LCM = 390150

Thus, we can understand that the LCM of 450,867,918 is 390150.
