Given numbers are 645,517,381,534

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

The LCM of 645,517,381,534 is 7538309790.

Find LCM of 645,517,381,534 with Prime Factorization

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

3 x 215 x 517 x 127 x 178 = 7538309790

Therefore, the lowest common multiple of 645,517,381,534 is 7538309790.

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.

645 x 517 x 381 x 534 = 67844788110

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

517 : 1, 11, 47, 517

381 : 1, 3, 127, 381

534 : 1, 2, 3, 6, 89, 178, 267, 534

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,517,381,534, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

517:11x 47

381:3x 127

534:2x 3x 89

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 67844788110/(1x9)

LCM = 67844788110/9

LCM = 7538309790

Thus, we can understand that the LCM of 645,517,381,534 is 7538309790.
