Given numbers are 278,809,153,454

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

The LCM of 278,809,153,454 is 7811071362.

Find LCM of 278,809,153,454 with Prime Factorization

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

2 x 139 x 809 x 153 x 227 = 7811071362

Therefore, the lowest common multiple of 278,809,153,454 is 7811071362.

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.

278 x 809 x 153 x 454 = 15622142724

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.

278 : 1, 2, 139, 278

809 : 1, 809

153 : 1, 3, 9, 17, 51, 153

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,809,153,454, is 1.

Now, the common factors can be found like this.

278:2x 139

809:809

153:3x 3x 17

454:2x 227

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

2 = 2

Therefore, the value for common factors is 2.

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 = 15622142724/(1x2)

LCM = 15622142724/2

LCM = 7811071362

Thus, we can understand that the LCM of 278,809,153,454 is 7811071362.
