Given numbers are 427,556,715,278,423

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

The LCM of 427,556,715,278,423 is 71804072340.

Find LCM of 427,556,715,278,423 with Prime Factorization

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

2 x 139 x 427 x 2 x 715 x 1 x 423 = 71804072340

Therefore, the lowest common multiple of 427,556,715,278,423 is 71804072340.

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.

427 x 556 x 715 x 278 x 423 = 19961532110520

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.

427 : 1, 7, 61, 427

556 : 1, 2, 4, 139, 278, 556

715 : 1, 5, 11, 13, 55, 65, 143, 715

278 : 1, 2, 139, 278

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,556,715,278,423, is 1.

Now, the common factors can be found like this.

427:7x 61

556:2x 2x 139

715:5x 11x 13

278:2x 139

423:3x 3x 47

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

2x 139 = 278

Therefore, the value for common factors is 278.

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 = 19961532110520/(1x278)

LCM = 19961532110520/278

LCM = 71804072340

Thus, we can understand that the LCM of 427,556,715,278,423 is 71804072340.
