Given numbers are 861,772,403,440

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

The LCM of 861,772,403,440 is 29465796360.

Find LCM of 861,772,403,440 with Prime Factorization

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

2 x 2 x 861 x 193 x 403 x 110 = 29465796360

Therefore, the lowest common multiple of 861,772,403,440 is 29465796360.

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.

861 x 772 x 403 x 440 = 117863185440

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

772 : 1, 2, 4, 193, 386, 772

403 : 1, 13, 31, 403

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 861,772,403,440, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

772:2x 2x 193

403:13x 31

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.

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 = 117863185440/(1x4)

LCM = 117863185440/4

LCM = 29465796360

Thus, we can understand that the LCM of 861,772,403,440 is 29465796360.
