Given numbers are 643,112,988,853

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

The LCM of 643,112,988,853 is 15173123056.

Find LCM of 643,112,988,853 with Prime Factorization

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

2 x 2 x 643 x 28 x 247 x 853 = 15173123056

Therefore, the lowest common multiple of 643,112,988,853 is 15173123056.

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.

643 x 112 x 988 x 853 = 60692492224

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.

643 : 1, 643

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,112,988,853, is 1.

Now, the common factors can be found like this.

643:643

112:2x 2x 2x 2x 7

988:2x 2x 13x 19

853:853

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 = 60692492224/(1x4)

LCM = 60692492224/4

LCM = 15173123056

Thus, we can understand that the LCM of 643,112,988,853 is 15173123056.
