Given numbers are 161,437,368,581

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

The LCM of 161,437,368,581 is 4062352.

Find LCM of 161,437,368,581 with Prime Factorization

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

7 x 23 x 1 x 19 x 16 x 83 = 4062352

Therefore, the lowest common multiple of 161,437,368,581 is 4062352.

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 368 x 581 = 15042889456

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

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,437,368,581, is 1.

Now, the common factors can be found like this.

161:7x 23

437:19x 23

368:2x 2x 2x 2x 23

581:7x 83

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

7x 23x 23 = 3703

Therefore, the value for common factors is 3703.

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 = 15042889456/(1x3703)

LCM = 15042889456/3703

LCM = 4062352

Thus, we can understand that the LCM of 161,437,368,581 is 4062352.
