Given numbers are 987,639,509,867

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

The LCM of 987,639,509,867 is 30925190331.

Find LCM of 987,639,509,867 with Prime Factorization

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

3 x 329 x 213 x 509 x 289 = 30925190331

Therefore, the lowest common multiple of 987,639,509,867 is 30925190331.

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.

987 x 639 x 509 x 867 = 278326712979

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.

987 : 1, 3, 7, 21, 47, 141, 329, 987

639 : 1, 3, 9, 71, 213, 639

509 : 1, 509

867 : 1, 3, 17, 51, 289, 867

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,639,509,867, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

639:3x 3x 71

509:509

867:3x 17x 17

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 = 278326712979/(1x9)

LCM = 278326712979/9

LCM = 30925190331

Thus, we can understand that the LCM of 987,639,509,867 is 30925190331.
