Calculate the LCM of 891,480,383,455

Given numbers are 891,480,383,455

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

The LCM of 891,480,383,455 is 4968643680.

Find LCM of 891,480,383,455 with Prime Factorization


3 891, 480, 383, 455
5 297, 160, 383, 455
297, 32, 383, 91

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

3 x 5 x 297 x 32 x 383 x 91 = 4968643680

Therefore, the lowest common multiple of 891,480,383,455 is 4968643680.

LCM Formula to Find Lowest Common Multiple of 891,480,383,455

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.

891 x 480 x 383 x 455 = 74529655200

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

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

383 : 1, 383

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,480,383,455, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

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

383:383

455:5x 7x 13

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 74529655200/(1x15)

LCM = 74529655200/15

LCM = 4968643680

Thus, we can understand that the LCM of 891,480,383,455 is 4968643680.
