Given numbers are 408,158,821,821

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

The LCM of 408,158,821,821 is 26462472.

Find LCM of 408,158,821,821 with Prime Factorization

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

2 x 821 x 204 x 79 x 1 x 1 = 26462472

Therefore, the lowest common multiple of 408,158,821,821 is 26462472.

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.

408 x 158 x 821 x 821 = 43451379024

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.

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

158 : 1, 2, 79, 158

821 : 1, 821

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,158,821,821, is 1.

Now, the common factors can be found like this.

408:2x 2x 2x 3x 17

158:2x 79

821:821

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 821 = 1642

Therefore, the value for common factors is 1642.

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 = 43451379024/(1x1642)

LCM = 43451379024/1642

LCM = 26462472

Thus, we can understand that the LCM of 408,158,821,821 is 26462472.
