Calculate the LCM of 449,486,315,768

Given numbers are 449,486,315,768

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

The LCM of 449,486,315,768 is 977598720.

Find LCM of 449,486,315,768 with Prime Factorization


2 449, 486, 315, 768
3 449, 243, 315, 384
3 449, 81, 105, 128
449, 27, 35, 128

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

2 x 3 x 3 x 449 x 27 x 35 x 128 = 977598720

Therefore, the lowest common multiple of 449,486,315,768 is 977598720.

LCM Formula to Find Lowest Common Multiple of 449,486,315,768

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.

449 x 486 x 315 x 768 = 52790330880

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.

449 : 1, 449

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,486,315,768, is 1.

Now, the common factors can be found like this.

449:449

486:2x 3x 3x 3x 3x 3

315:3x 3x 5x 7

768:2x 2x 2x 2x 2x 2x 2x 2x 3

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 52790330880/(1x54)

LCM = 52790330880/54

LCM = 977598720

Thus, we can understand that the LCM of 449,486,315,768 is 977598720.
