Given numbers are 161,437,285,664

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

The LCM of 161,437,285,664 is 30467640.

Find LCM of 161,437,285,664 with Prime Factorization

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

19 x 23 x 7 x 1 x 15 x 664 = 30467640

Therefore, the lowest common multiple of 161,437,285,664 is 30467640.

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.

161 x 437 x 285 x 664 = 13314358680

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.

161 : 1, 7, 23, 161

437 : 1, 19, 23, 437

285 : 1, 3, 5, 15, 19, 57, 95, 285

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,437,285,664, is 1.

Now, the common factors can be found like this.

161:7x 23

437:19x 23

285:3x 5x 19

664:2x 2x 2x 83

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

19x 23 = 437

Therefore, the value for common factors is 437.

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 = 13314358680/(1x437)

LCM = 13314358680/437

LCM = 30467640

Thus, we can understand that the LCM of 161,437,285,664 is 30467640.
