Given numbers are 662,928,278,477,821

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

The LCM of 662,928,278,477,821 is 16720617281184.

Find LCM of 662,928,278,477,821 with Prime Factorization

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

2 x 331 x 464 x 139 x 477 x 821 = 16720617281184

Therefore, the lowest common multiple of 662,928,278,477,821 is 16720617281184.

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.

662 x 928 x 278 x 477 x 821 = 66882469124736

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.

662 : 1, 2, 331, 662

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

278 : 1, 2, 139, 278

477 : 1, 3, 9, 53, 159, 477

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,928,278,477,821, is 1.

Now, the common factors can be found like this.

662:2x 331

928:2x 2x 2x 2x 2x 29

278:2x 139

477:3x 3x 53

821:821

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 = 66882469124736/(1x4)

LCM = 66882469124736/4

LCM = 16720617281184

Thus, we can understand that the LCM of 662,928,278,477,821 is 16720617281184.
