Given numbers are 554,378,445,406

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

The LCM of 554,378,445,406 is 1351230930.

Find LCM of 554,378,445,406 with Prime Factorization

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

2 x 7 x 277 x 27 x 445 x 29 = 1351230930

Therefore, the lowest common multiple of 554,378,445,406 is 1351230930.

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.

554 x 378 x 445 x 406 = 37834466040

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.

554 : 1, 2, 277, 554

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

445 : 1, 5, 89, 445

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,378,445,406, is 1.

Now, the common factors can be found like this.

554:2x 277

378:2x 3x 3x 3x 7

445:5x 89

406:2x 7x 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 7 = 28

Therefore, the value for common factors is 28.

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 = 37834466040/(1x28)

LCM = 37834466040/28

LCM = 1351230930

Thus, we can understand that the LCM of 554,378,445,406 is 1351230930.
