Given numbers are 227,301,330,638

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

The LCM of 227,301,330,638 is 653889390.

Find LCM of 227,301,330,638 with Prime Factorization

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

2 x 11 x 227 x 301 x 15 x 29 = 653889390

Therefore, the lowest common multiple of 227,301,330,638 is 653889390.

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.

227 x 301 x 330 x 638 = 14385566580

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.

227 : 1, 227

301 : 1, 7, 43, 301

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,301,330,638, is 1.

Now, the common factors can be found like this.

227:227

301:7x 43

330:2x 3x 5x 11

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 14385566580/(1x22)

LCM = 14385566580/22

LCM = 653889390

Thus, we can understand that the LCM of 227,301,330,638 is 653889390.

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