Given numbers are 409,221,117,103

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

The LCM of 409,221,117,103 is 83790603.

Find LCM of 409,221,117,103 with Prime Factorization

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

13 x 409 x 17 x 9 x 103 = 83790603

Therefore, the lowest common multiple of 409,221,117,103 is 83790603.

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.

409 x 221 x 117 x 103 = 1089277839

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.

409 : 1, 409

221 : 1, 13, 17, 221

117 : 1, 3, 9, 13, 39, 117

103 : 1, 103

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,221,117,103, is 1.

Now, the common factors can be found like this.

409:409

221:13x 17

117:3x 3x 13

103:103

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 = 1089277839/(1x13)

LCM = 1089277839/13

LCM = 83790603

Thus, we can understand that the LCM of 409,221,117,103 is 83790603.
