Given numbers are 721,473,323,198,349

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

The LCM of 721,473,323,198,349 is 691985285838.

Find LCM of 721,473,323,198,349 with Prime Factorization

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

11 x 721 x 43 x 323 x 18 x 349 = 691985285838

Therefore, the lowest common multiple of 721,473,323,198,349 is 691985285838.

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.

721 x 473 x 323 x 198 x 349 = 7611838144218

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.

721 : 1, 7, 103, 721

473 : 1, 11, 43, 473

323 : 1, 17, 19, 323

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,473,323,198,349, is 1.

Now, the common factors can be found like this.

721:7x 103

473:11x 43

323:17x 19

198:2x 3x 3x 11

349:349

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

11 = 11

Therefore, the value for common factors is 11.

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 = 7611838144218/(1x11)

LCM = 7611838144218/11

LCM = 691985285838

Thus, we can understand that the LCM of 721,473,323,198,349 is 691985285838.
