Given numbers are 638,372,986,982,816

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

The LCM of 638,372,986,982,816 is 3962087184.

Find LCM of 638,372,986,982,816 with Prime Factorization

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

2 x 2 x 3 x 17 x 29 x 11 x 31 x 1 x 491 x 4 = 3962087184

Therefore, the lowest common multiple of 638,372,986,982,816 is 3962087184.

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.

638 x 372 x 986 x 982 x 816 = 187517662244352

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

986 : 1, 2, 17, 29, 34, 58, 493, 986

982 : 1, 2, 491, 982

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,372,986,982,816, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

372:2x 2x 3x 31

986:2x 17x 29

982:2x 491

816:2x 2x 2x 2x 3x 17

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

2x 2x 2x 2x 3x 17x 29 = 23664

Therefore, the value for common factors is 23664.

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 = 187517662244352/(2x23664)

LCM = 187517662244352/47328

LCM = 3962087184

Thus, we can understand that the LCM of 638,372,986,982,816 is 3962087184.
