Given numbers are 398,415,761,859,778

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

The LCM of 398,415,761,859,778 is 42000899429870.

Find LCM of 398,415,761,859,778 with Prime Factorization

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

2 x 199 x 415 x 761 x 859 x 389 = 42000899429870

Therefore, the lowest common multiple of 398,415,761,859,778 is 42000899429870.

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.

398 x 415 x 761 x 859 x 778 = 84001798859740

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.

398 : 1, 2, 199, 398

415 : 1, 5, 83, 415

761 : 1, 761

859 : 1, 859

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,415,761,859,778, is 1.

Now, the common factors can be found like this.

398:2x 199

415:5x 83

761:761

859:859

778:2x 389

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 = 84001798859740/(1x2)

LCM = 84001798859740/2

LCM = 42000899429870

Thus, we can understand that the LCM of 398,415,761,859,778 is 42000899429870.
