Given numbers are 731,706,221

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

The LCM of 731,706,221 is 6709118.

Find LCM of 731,706,221 with Prime Factorization

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

17 x 43 x 706 x 13 = 6709118

Therefore, the lowest common multiple of 731,706,221 is 6709118.

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.

731 x 706 x 221 = 114055006

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.

731 : 1, 17, 43, 731

706 : 1, 2, 353, 706

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,706,221, is 1.

Now, the common factors can be found like this.

731:17x 43

706:2x 353

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.

17 = 17

Therefore, the value for common factors is 17.

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 = 114055006/(1x17)

LCM = 114055006/17

LCM = 6709118

Thus, we can understand that the LCM of 731,706,221 is 6709118.

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

• LCM of 637, 896, 542
• LCM of 253, 489, 385
