Given numbers are 278,558,248,551

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

The LCM of 278,558,248,551 is 170946648.

Find LCM of 278,558,248,551 with Prime Factorization

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

2 x 31 x 139 x 9 x 4 x 551 = 170946648

Therefore, the lowest common multiple of 278,558,248,551 is 170946648.

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 558 x 248 x 551 = 21197384352

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

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

248 : 1, 2, 4, 8, 31, 62, 124, 248

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,558,248,551, is 1.

Now, the common factors can be found like this.

278:2x 139

558:2x 3x 3x 31

248:2x 2x 2x 31

551:19x 29

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 31 = 124

Therefore, the value for common factors is 124.

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 = 21197384352/(1x124)

LCM = 21197384352/124

LCM = 170946648

Thus, we can understand that the LCM of 278,558,248,551 is 170946648.
