Given numbers are 155,440,366,731

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

The LCM of 155,440,366,731 is 1824663720.

Find LCM of 155,440,366,731 with Prime Factorization

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

2 x 5 x 31 x 44 x 183 x 731 = 1824663720

Therefore, the lowest common multiple of 155,440,366,731 is 1824663720.

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.

155 x 440 x 366 x 731 = 18246637200

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.

155 : 1, 5, 31, 155

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

366 : 1, 2, 3, 6, 61, 122, 183, 366

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,440,366,731, is 1.

Now, the common factors can be found like this.

155:5x 31

440:2x 2x 2x 5x 11

366:2x 3x 61

731:17x 43

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 18246637200/(1x10)

LCM = 18246637200/10

LCM = 1824663720

Thus, we can understand that the LCM of 155,440,366,731 is 1824663720.

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