Given numbers are 787,444,217,428

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

The LCM of 787,444,217,428 is 8113368732.

Find LCM of 787,444,217,428 with Prime Factorization

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

2 x 2 x 787 x 111 x 217 x 107 = 8113368732

Therefore, the lowest common multiple of 787,444,217,428 is 8113368732.

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.

787 x 444 x 217 x 428 = 32453474928

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.

787 : 1, 787

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

217 : 1, 7, 31, 217

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,444,217,428, is 1.

Now, the common factors can be found like this.

787:787

444:2x 2x 3x 37

217:7x 31

428:2x 2x 107

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 = 32453474928/(1x4)

LCM = 32453474928/4

LCM = 8113368732

Thus, we can understand that the LCM of 787,444,217,428 is 8113368732.
