Given numbers are 722,143,221

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

The LCM of 722,143,221 is 1755182.

Find LCM of 722,143,221 with Prime Factorization

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

13 x 722 x 11 x 17 = 1755182

Therefore, the lowest common multiple of 722,143,221 is 1755182.

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 143 x 221 = 22817366

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

143 : 1, 11, 13, 143

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,143,221, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

143:11x 13

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 22817366/(1x13)

LCM = 22817366/13

LCM = 1755182

Thus, we can understand that the LCM of 722,143,221 is 1755182.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 949, 125, 567
• LCM of 786, 514, 539
