Given numbers are 821,328,791,964

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

The LCM of 821,328,791,964 is 51334640728.

Find LCM of 821,328,791,964 with Prime Factorization

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

2 x 2 x 821 x 82 x 791 x 241 = 51334640728

Therefore, the lowest common multiple of 821,328,791,964 is 51334640728.

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.

821 x 328 x 791 x 964 = 205338562912

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.

821 : 1, 821

328 : 1, 2, 4, 8, 41, 82, 164, 328

791 : 1, 7, 113, 791

964 : 1, 2, 4, 241, 482, 964

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,328,791,964, is 1.

Now, the common factors can be found like this.

821:821

328:2x 2x 2x 41

791:7x 113

964:2x 2x 241

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 205338562912/(1x4)

LCM = 205338562912/4

LCM = 51334640728

Thus, we can understand that the LCM of 821,328,791,964 is 51334640728.
