Given numbers are 394,280,343,747

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

The LCM of 394,280,343,747 is 2019021480.

Find LCM of 394,280,343,747 with Prime Factorization

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

2 x 7 x 197 x 20 x 49 x 747 = 2019021480

Therefore, the lowest common multiple of 394,280,343,747 is 2019021480.

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.

394 x 280 x 343 x 747 = 28266300720

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.

394 : 1, 2, 197, 394

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

343 : 1, 7, 49, 343

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,280,343,747, is 1.

Now, the common factors can be found like this.

394:2x 197

280:2x 2x 2x 5x 7

343:7x 7x 7

747:3x 3x 83

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 28266300720/(1x14)

LCM = 28266300720/14

LCM = 2019021480

Thus, we can understand that the LCM of 394,280,343,747 is 2019021480.
