Given numbers are 821,764,134,905

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

The LCM of 821,764,134,905 is 38032939940.

Find LCM of 821,764,134,905 with Prime Factorization

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

2 x 821 x 382 x 67 x 905 = 38032939940

Therefore, the lowest common multiple of 821,764,134,905 is 38032939940.

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 764 x 134 x 905 = 76065879880

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

764 : 1, 2, 4, 191, 382, 764

134 : 1, 2, 67, 134

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,764,134,905, is 1.

Now, the common factors can be found like this.

821:821

764:2x 2x 191

134:2x 67

905:5x 181

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 = 76065879880/(1x2)

LCM = 76065879880/2

LCM = 38032939940

Thus, we can understand that the LCM of 821,764,134,905 is 38032939940.
