Given numbers are 398,381,889,544

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

The LCM of 398,381,889,544 is 288718752.

Find LCM of 398,381,889,544 with Prime Factorization

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

2 x 127 x 199 x 3 x 7 x 272 = 288718752

Therefore, the lowest common multiple of 398,381,889,544 is 288718752.

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.

398 x 381 x 889 x 544 = 73334563008

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.

398 : 1, 2, 199, 398

381 : 1, 3, 127, 381

889 : 1, 7, 127, 889

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,381,889,544, is 1.

Now, the common factors can be found like this.

398:2x 199

381:3x 127

889:7x 127

544:2x 2x 2x 2x 2x 17

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 73334563008/(1x254)

LCM = 73334563008/254

LCM = 288718752

Thus, we can understand that the LCM of 398,381,889,544 is 288718752.
