Given numbers are 862,378,643,397

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

The LCM of 862,378,643,397 is 41588240778.

Find LCM of 862,378,643,397 with Prime Factorization

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

2 x 431 x 189 x 643 x 397 = 41588240778

Therefore, the lowest common multiple of 862,378,643,397 is 41588240778.

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.

862 x 378 x 643 x 397 = 83176481556

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.

862 : 1, 2, 431, 862

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

643 : 1, 643

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,378,643,397, is 1.

Now, the common factors can be found like this.

862:2x 431

378:2x 3x 3x 3x 7

643:643

397:397

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

2 = 2

Therefore, the value for common factors is 2.

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 = 83176481556/(1x2)

LCM = 83176481556/2

LCM = 41588240778

Thus, we can understand that the LCM of 862,378,643,397 is 41588240778.
