Given numbers are 318,278,689,397

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

The LCM of 318,278,689,397 is 228126522.

Find LCM of 318,278,689,397 with Prime Factorization

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

2 x 53 x 3 x 139 x 13 x 397 = 228126522

Therefore, the lowest common multiple of 318,278,689,397 is 228126522.

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.

318 x 278 x 689 x 397 = 24181411332

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.

318 : 1, 2, 3, 6, 53, 106, 159, 318

278 : 1, 2, 139, 278

689 : 1, 13, 53, 689

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,278,689,397, is 1.

Now, the common factors can be found like this.

318:2x 3x 53

278:2x 139

689:13x 53

397:397

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 24181411332/(1x106)

LCM = 24181411332/106

LCM = 228126522

Thus, we can understand that the LCM of 318,278,689,397 is 228126522.
