Given numbers are 221,642,161,376

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

The LCM of 221,642,161,376 is 4294484376.

Find LCM of 221,642,161,376 with Prime Factorization

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

2 x 221 x 321 x 161 x 188 = 4294484376

Therefore, the lowest common multiple of 221,642,161,376 is 4294484376.

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.

221 x 642 x 161 x 376 = 8588968752

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.

221 : 1, 13, 17, 221

642 : 1, 2, 3, 6, 107, 214, 321, 642

161 : 1, 7, 23, 161

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,642,161,376, is 1.

Now, the common factors can be found like this.

221:13x 17

642:2x 3x 107

161:7x 23

376:2x 2x 2x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 8588968752/(1x2)

LCM = 8588968752/2

LCM = 4294484376

Thus, we can understand that the LCM of 221,642,161,376 is 4294484376.
