Given numbers are 581,146,618,821

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

The LCM of 581,146,618,821 is 21519423114.

Find LCM of 581,146,618,821 with Prime Factorization

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

2 x 581 x 73 x 309 x 821 = 21519423114

Therefore, the lowest common multiple of 581,146,618,821 is 21519423114.

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.

581 x 146 x 618 x 821 = 43038846228

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.

581 : 1, 7, 83, 581

146 : 1, 2, 73, 146

618 : 1, 2, 3, 6, 103, 206, 309, 618

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,146,618,821, is 1.

Now, the common factors can be found like this.

581:7x 83

146:2x 73

618:2x 3x 103

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.

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 = 43038846228/(1x2)

LCM = 43038846228/2

LCM = 21519423114

Thus, we can understand that the LCM of 581,146,618,821 is 21519423114.
