Given numbers are 278,647,417,571

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

The LCM of 278,647,417,571 is 308110458.

Find LCM of 278,647,417,571 with Prime Factorization

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

139 x 2 x 647 x 3 x 571 = 308110458

Therefore, the lowest common multiple of 278,647,417,571 is 308110458.

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 417 x 571 = 42827353662

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

417 : 1, 3, 139, 417

571 : 1, 571

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,647,417,571, is 1.

Now, the common factors can be found like this.

278:2x 139

647:647

417:3x 139

571:571

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

139 = 139

Therefore, the value for common factors is 139.

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 = 42827353662/(1x139)

LCM = 42827353662/139

LCM = 308110458

Thus, we can understand that the LCM of 278,647,417,571 is 308110458.
