Given numbers are 278,831,690,446

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

The LCM of 278,831,690,446 is 5924456610.

Find LCM of 278,831,690,446 with Prime Factorization

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

2 x 3 x 139 x 277 x 115 x 223 = 5924456610

Therefore, the lowest common multiple of 278,831,690,446 is 5924456610.

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.

278 x 831 x 690 x 446 = 71093479320

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.

278 : 1, 2, 139, 278

831 : 1, 3, 277, 831

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,831,690,446, is 1.

Now, the common factors can be found like this.

278:2x 139

831:3x 277

690:2x 3x 5x 23

446:2x 223

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 3 = 12

Therefore, the value for common factors is 12.

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 = 71093479320/(1x12)

LCM = 71093479320/12

LCM = 5924456610

Thus, we can understand that the LCM of 278,831,690,446 is 5924456610.
