Given numbers are 383,163,422,780,689

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

The LCM of 383,163,422,780,689 is 544551935460.

Find LCM of 383,163,422,780,689 with Prime Factorization

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

2 x 13 x 383 x 163 x 211 x 30 x 53 = 544551935460

Therefore, the lowest common multiple of 383,163,422,780,689 is 544551935460.

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.

383 x 163 x 422 x 780 x 689 = 14158350321960

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.

383 : 1, 383

163 : 1, 163

422 : 1, 2, 211, 422

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 383,163,422,780,689, is 1.

Now, the common factors can be found like this.

383:383

163:163

422:2x 211

780:2x 2x 3x 5x 13

689:13x 53

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 14158350321960/(1x26)

LCM = 14158350321960/26

LCM = 544551935460

Thus, we can understand that the LCM of 383,163,422,780,689 is 544551935460.
