Given numbers are 278,446,474,974

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

The LCM of 278,446,474,974 is 7155285486.

Find LCM of 278,446,474,974 with Prime Factorization

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

2 x 139 x 223 x 237 x 487 = 7155285486

Therefore, the lowest common multiple of 278,446,474,974 is 7155285486.

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 446 x 474 x 974 = 57242283888

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

446 : 1, 2, 223, 446

474 : 1, 2, 3, 6, 79, 158, 237, 474

974 : 1, 2, 487, 974

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,446,474,974, is 2.

Now, the common factors can be found like this.

278:2x 139

446:2x 223

474:2x 3x 79

974:2x 487

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 57242283888/(2x4)

LCM = 57242283888/8

LCM = 7155285486

Thus, we can understand that the LCM of 278,446,474,974 is 7155285486.
