Given numbers are 426,354,691,821

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

The LCM of 426,354,691,821 is 14258794674.

Find LCM of 426,354,691,821 with Prime Factorization

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

2 x 3 x 71 x 59 x 691 x 821 = 14258794674

Therefore, the lowest common multiple of 426,354,691,821 is 14258794674.

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.

426 x 354 x 691 x 821 = 85552768044

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

354 : 1, 2, 3, 6, 59, 118, 177, 354

691 : 1, 691

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,354,691,821, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

354:2x 3x 59

691:691

821:821

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 = 85552768044/(1x6)

LCM = 85552768044/6

LCM = 14258794674

Thus, we can understand that the LCM of 426,354,691,821 is 14258794674.
