Given numbers are 489,904,620

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

The LCM of 489,904,620 is 68518680.

Find LCM of 489,904,620 with Prime Factorization

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

2 x 2 x 489 x 226 x 155 = 68518680

Therefore, the lowest common multiple of 489,904,620 is 68518680.

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.

489 x 904 x 620 = 274074720

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.

489 : 1, 3, 163, 489

904 : 1, 2, 4, 8, 113, 226, 452, 904

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,904,620, is 1.

Now, the common factors can be found like this.

489:3x 163

904:2x 2x 2x 113

620:2x 2x 5x 31

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 = 274074720/(1x4)

LCM = 274074720/4

LCM = 68518680

Thus, we can understand that the LCM of 489,904,620 is 68518680.

Here are some samples of LCM of two or more Numbers calculations.
