Given numbers are 784,687,141,394

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

The LCM of 784,687,141,394 is 4986971472.

Find LCM of 784,687,141,394 with Prime Factorization

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

2 x 3 x 392 x 229 x 47 x 197 = 4986971472

Therefore, the lowest common multiple of 784,687,141,394 is 4986971472.

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.

784 x 687 x 141 x 394 = 29921828832

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.

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

687 : 1, 3, 229, 687

141 : 1, 3, 47, 141

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,687,141,394, is 1.

Now, the common factors can be found like this.

784:2x 2x 2x 2x 7x 7

687:3x 229

141:3x 47

394:2x 197

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 29921828832/(1x6)

LCM = 29921828832/6

LCM = 4986971472

Thus, we can understand that the LCM of 784,687,141,394 is 4986971472.
