Given numbers are 103,646,221

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

The LCM of 103,646,221 is 864994.

Find LCM of 103,646,221 with Prime Factorization

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

17 x 103 x 38 x 13 = 864994

Therefore, the lowest common multiple of 103,646,221 is 864994.

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.

103 x 646 x 221 = 14704898

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.

103 : 1, 103

646 : 1, 2, 17, 19, 34, 38, 323, 646

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,646,221, is 1.

Now, the common factors can be found like this.

103:103

646:2x 17x 19

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 = 14704898/(1x17)

LCM = 14704898/17

LCM = 864994

Thus, we can understand that the LCM of 103,646,221 is 864994.

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

• LCM of 613, 794, 938
• LCM of 965, 755, 816
