Given numbers are 517,207,440

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

The LCM of 517,207,440 is 4280760.

Find LCM of 517,207,440 with Prime Factorization

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

11 x 47 x 207 x 40 = 4280760

Therefore, the lowest common multiple of 517,207,440 is 4280760.

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.

517 x 207 x 440 = 47088360

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.

517 : 1, 11, 47, 517

207 : 1, 3, 9, 23, 69, 207

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,207,440, is 1.

Now, the common factors can be found like this.

517:11x 47

207:3x 3x 23

440:2x 2x 2x 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.

11 = 11

Therefore, the value for common factors is 11.

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 = 47088360/(1x11)

LCM = 47088360/11

LCM = 4280760

Thus, we can understand that the LCM of 517,207,440 is 4280760.
