Given numbers are 517,380,394,278

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

The LCM of 517,380,394,278 is 5379664180.

Find LCM of 517,380,394,278 with Prime Factorization

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

2 x 517 x 190 x 197 x 139 = 5379664180

Therefore, the lowest common multiple of 517,380,394,278 is 5379664180.

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.

517 x 380 x 394 x 278 = 21518656720

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.

517 : 1, 11, 47, 517

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

394 : 1, 2, 197, 394

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,380,394,278, is 1.

Now, the common factors can be found like this.

517:11x 47

380:2x 2x 5x 19

394:2x 197

278:2x 139

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 21518656720/(1x4)

LCM = 21518656720/4

LCM = 5379664180

Thus, we can understand that the LCM of 517,380,394,278 is 5379664180.
