Given numbers are 432,239,117,646

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

The LCM of 432,239,117,646 is 433538352.

Find LCM of 432,239,117,646 with Prime Factorization

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

2 x 3 x 3 x 24 x 239 x 13 x 323 = 433538352

Therefore, the lowest common multiple of 432,239,117,646 is 433538352.

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.

432 x 239 x 117 x 646 = 7803690336

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.

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

239 : 1, 239

117 : 1, 3, 9, 13, 39, 117

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,239,117,646, is 1.

Now, the common factors can be found like this.

432:2x 2x 2x 2x 3x 3x 3

239:239

117:3x 3x 13

646:2x 17x 19

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 7803690336/(1x18)

LCM = 7803690336/18

LCM = 433538352

Thus, we can understand that the LCM of 432,239,117,646 is 433538352.
