Given numbers are 905,411,622,380

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

The LCM of 905,411,622,380 is 8791528380.

Find LCM of 905,411,622,380 with Prime Factorization

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

2 x 5 x 181 x 411 x 311 x 38 = 8791528380

Therefore, the lowest common multiple of 905,411,622,380 is 8791528380.

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.

905 x 411 x 622 x 380 = 87915283800

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.

905 : 1, 5, 181, 905

411 : 1, 3, 137, 411

622 : 1, 2, 311, 622

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,411,622,380, is 1.

Now, the common factors can be found like this.

905:5x 181

411:3x 137

622:2x 311

380:2x 2x 5x 19

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 87915283800/(1x10)

LCM = 87915283800/10

LCM = 8791528380

Thus, we can understand that the LCM of 905,411,622,380 is 8791528380.
