Given numbers are 382,172,649

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

The LCM of 382,172,649 is 21320948.

Find LCM of 382,172,649 with Prime Factorization

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

2 x 191 x 86 x 649 = 21320948

Therefore, the lowest common multiple of 382,172,649 is 21320948.

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.

382 x 172 x 649 = 42641896

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.

382 : 1, 2, 191, 382

172 : 1, 2, 4, 43, 86, 172

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,172,649, is 1.

Now, the common factors can be found like this.

382:2x 191

172:2x 2x 43

649:11x 59

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42641896/(1x2)

LCM = 42641896/2

LCM = 21320948

Thus, we can understand that the LCM of 382,172,649 is 21320948.

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

• LCM of 949, 302, 220
• LCM of 912, 650, 693
