Given numbers are 364,391,821,540

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

The LCM of 364,391,821,540 is 15774480540.

Find LCM of 364,391,821,540 with Prime Factorization

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

2 x 2 x 91 x 391 x 821 x 135 = 15774480540

Therefore, the lowest common multiple of 364,391,821,540 is 15774480540.

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.

364 x 391 x 821 x 540 = 63097922160

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.

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

391 : 1, 17, 23, 391

821 : 1, 821

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,391,821,540, is 1.

Now, the common factors can be found like this.

364:2x 2x 7x 13

391:17x 23

821:821

540:2x 2x 3x 3x 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 = 63097922160/(1x4)

LCM = 63097922160/4

LCM = 15774480540

Thus, we can understand that the LCM of 364,391,821,540 is 15774480540.
