Given numbers are 646,136,442,199

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

The LCM of 646,136,442,199 is 6684808.

Find LCM of 646,136,442,199 with Prime Factorization

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

2 x 17 x 19 x 4 x 13 x 199 = 6684808

Therefore, the lowest common multiple of 646,136,442,199 is 6684808.

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.

646 x 136 x 442 x 199 = 7727638048

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

136 : 1, 2, 4, 8, 17, 34, 68, 136

442 : 1, 2, 13, 17, 26, 34, 221, 442

199 : 1, 199

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,136,442,199, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

136:2x 2x 2x 17

442:2x 13x 17

199:199

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 17x 17 = 1156

Therefore, the value for common factors is 1156.

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 = 7727638048/(1x1156)

LCM = 7727638048/1156

LCM = 6684808

Thus, we can understand that the LCM of 646,136,442,199 is 6684808.
