Given numbers are 722,515,221,164

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

The LCM of 722,515,221,164 is 6738303260.

Find LCM of 722,515,221,164 with Prime Factorization

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

2 x 361 x 515 x 221 x 82 = 6738303260

Therefore, the lowest common multiple of 722,515,221,164 is 6738303260.

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.

722 x 515 x 221 x 164 = 13476606520

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.

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

515 : 1, 5, 103, 515

221 : 1, 13, 17, 221

164 : 1, 2, 4, 41, 82, 164

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,515,221,164, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

515:5x 103

221:13x 17

164:2x 2x 41

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 = 13476606520/(1x2)

LCM = 13476606520/2

LCM = 6738303260

Thus, we can understand that the LCM of 722,515,221,164 is 6738303260.
