Given numbers are 221,814,722,781

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

The LCM of 221,814,722,781 is 4610863114.

Find LCM of 221,814,722,781 with Prime Factorization

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

2 x 11 x 221 x 37 x 361 x 71 = 4610863114

Therefore, the lowest common multiple of 221,814,722,781 is 4610863114.

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 814 x 722 x 781 = 101438988508

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

814 : 1, 2, 11, 22, 37, 74, 407, 814

722 : 1, 2, 19, 38, 361, 722

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,814,722,781, is 1.

Now, the common factors can be found like this.

221:13x 17

814:2x 11x 37

722:2x 19x 19

781:11x 71

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 101438988508/(1x22)

LCM = 101438988508/22

LCM = 4610863114

Thus, we can understand that the LCM of 221,814,722,781 is 4610863114.
