Given numbers are 361,821,308,480

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

The LCM of 361,821,308,480 is 10954241760.

Find LCM of 361,821,308,480 with Prime Factorization

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

2 x 2 x 361 x 821 x 77 x 120 = 10954241760

Therefore, the lowest common multiple of 361,821,308,480 is 10954241760.

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.

361 x 821 x 308 x 480 = 43816967040

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.

361 : 1, 19, 361

821 : 1, 821

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,821,308,480, is 1.

Now, the common factors can be found like this.

361:19x 19

821:821

308:2x 2x 7x 11

480:2x 2x 2x 2x 2x 3x 5

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 43816967040/(1x4)

LCM = 43816967040/4

LCM = 10954241760

Thus, we can understand that the LCM of 361,821,308,480 is 10954241760.
