Given numbers are 221,765,712

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

The LCM of 221,765,712 is 7080840.

Find LCM of 221,765,712 with Prime Factorization

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

17 x 13 x 45 x 712 = 7080840

Therefore, the lowest common multiple of 221,765,712 is 7080840.

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 765 x 712 = 120374280

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

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

712 : 1, 2, 4, 8, 89, 178, 356, 712

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,765,712, is 1.

Now, the common factors can be found like this.

221:13x 17

765:3x 3x 5x 17

712:2x 2x 2x 89

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 = 120374280/(1x17)

LCM = 120374280/17

LCM = 7080840

Thus, we can understand that the LCM of 221,765,712 is 7080840.

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