Given numbers are 801,121,478,578

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

The LCM of 801,121,478,578 is 13388860782.

Find LCM of 801,121,478,578 with Prime Factorization

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

2 x 801 x 121 x 239 x 289 = 13388860782

Therefore, the lowest common multiple of 801,121,478,578 is 13388860782.

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.

801 x 121 x 478 x 578 = 26777721564

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.

801 : 1, 3, 9, 89, 267, 801

121 : 1, 11, 121

478 : 1, 2, 239, 478

578 : 1, 2, 17, 34, 289, 578

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,121,478,578, is 1.

Now, the common factors can be found like this.

801:3x 3x 89

121:11x 11

478:2x 239

578:2x 17x 17

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 = 26777721564/(1x2)

LCM = 26777721564/2

LCM = 13388860782

Thus, we can understand that the LCM of 801,121,478,578 is 13388860782.
