Given numbers are 209,409,663,403

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

The LCM of 209,409,663,403 is 1756890993.

Find LCM of 209,409,663,403 with Prime Factorization

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

13 x 209 x 409 x 51 x 31 = 1756890993

Therefore, the lowest common multiple of 209,409,663,403 is 1756890993.

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.

209 x 409 x 663 x 403 = 22839582909

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.

209 : 1, 11, 19, 209

409 : 1, 409

663 : 1, 3, 13, 17, 39, 51, 221, 663

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,409,663,403, is 1.

Now, the common factors can be found like this.

209:11x 19

409:409

663:3x 13x 17

403:13x 31

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 = 22839582909/(1x13)

LCM = 22839582909/13

LCM = 1756890993

Thus, we can understand that the LCM of 209,409,663,403 is 1756890993.
