Given numbers are 415,278,780,574

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

The LCM of 415,278,780,574 is 2582672820.

Find LCM of 415,278,780,574 with Prime Factorization

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

2 x 5 x 83 x 139 x 78 x 287 = 2582672820

Therefore, the lowest common multiple of 415,278,780,574 is 2582672820.

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.

415 x 278 x 780 x 574 = 51653456400

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.

415 : 1, 5, 83, 415

278 : 1, 2, 139, 278

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

574 : 1, 2, 7, 14, 41, 82, 287, 574

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 415,278,780,574, is 1.

Now, the common factors can be found like this.

415:5x 83

278:2x 139

780:2x 2x 3x 5x 13

574:2x 7x 41

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 51653456400/(1x20)

LCM = 51653456400/20

LCM = 2582672820

Thus, we can understand that the LCM of 415,278,780,574 is 2582672820.
