Given numbers are 409,989,818,697

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

The LCM of 409,989,818,697 is 563874394.

Find LCM of 409,989,818,697 with Prime Factorization

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

409 x 1 x 989 x 2 x 697 = 563874394

Therefore, the lowest common multiple of 409,989,818,697 is 563874394.

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 989 x 818 x 697 = 230624627146

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

989 : 1, 23, 43, 989

818 : 1, 2, 409, 818

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,989,818,697, is 1.

Now, the common factors can be found like this.

409:409

989:23x 43

818:2x 409

697:17x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

409 = 409

Therefore, the value for common factors is 409.

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 = 230624627146/(1x409)

LCM = 230624627146/409

LCM = 563874394

Thus, we can understand that the LCM of 409,989,818,697 is 563874394.
