Given numbers are 278,445,389,554

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

The LCM of 278,445,389,554 is 13330123630.

Find LCM of 278,445,389,554 with Prime Factorization

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

2 x 139 x 445 x 389 x 277 = 13330123630

Therefore, the lowest common multiple of 278,445,389,554 is 13330123630.

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 445 x 389 x 554 = 26660247260

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

445 : 1, 5, 89, 445

389 : 1, 389

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,445,389,554, is 1.

Now, the common factors can be found like this.

278:2x 139

445:5x 89

389:389

554:2x 277

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

2 = 2

Therefore, the value for common factors is 2.

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 = 26660247260/(1x2)

LCM = 26660247260/2

LCM = 13330123630

Thus, we can understand that the LCM of 278,445,389,554 is 13330123630.
