Given numbers are 278,647,667,647

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

The LCM of 278,647,667,647 is 119970622.

Find LCM of 278,647,667,647 with Prime Factorization

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

647 x 278 x 1 x 667 x 1 = 119970622

Therefore, the lowest common multiple of 278,647,667,647 is 119970622.

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 647 x 667 x 647 = 77620992434

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

647 : 1, 647

667 : 1, 23, 29, 667

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,647,667,647, is 1.

Now, the common factors can be found like this.

278:2x 139

647:647

667:23x 29

647:647

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

647 = 647

Therefore, the value for common factors is 647.

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 = 77620992434/(1x647)

LCM = 77620992434/647

LCM = 119970622

Thus, we can understand that the LCM of 278,647,667,647 is 119970622.
