LCM of:

Calculate the LCM of 399,794,840,495

Given numbers are 399,794,840,495

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

The LCM of 399,794,840,495 is 209091960.

Find LCM of 399,794,840,495 with Prime Factorization


2 399, 794, 840, 495
3 399, 397, 420, 495
5 133, 397, 140, 165
7 133, 397, 28, 33
19, 397, 4, 33

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

2 x 3 x 5 x 7 x 19 x 397 x 4 x 33 = 209091960

Therefore, the lowest common multiple of 399,794,840,495 is 209091960.

LCM Formula to Find Lowest Common Multiple of 399,794,840,495

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.

399 x 794 x 840 x 495 = 131727934800

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

794 : 1, 2, 397, 794

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,794,840,495, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

794:2x 397

840:2x 2x 2x 3x 5x 7

495:3x 3x 5x 11

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 5x 7 = 630

Therefore, the value for common factors is 630.

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 = 131727934800/(1x630)

LCM = 131727934800/630

LCM = 209091960

Thus, we can understand that the LCM of 399,794,840,495 is 209091960.
