Given numbers are 721,547,891,341,974

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

The LCM of 721,547,891,341,974 is 10610135880498.

Find LCM of 721,547,891,341,974 with Prime Factorization

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

11 x 721 x 547 x 81 x 31 x 974 = 10610135880498

Therefore, the lowest common multiple of 721,547,891,341,974 is 10610135880498.

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 547 x 891 x 341 x 974 = 116711494685478

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

547 : 1, 547

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

341 : 1, 11, 31, 341

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,547,891,341,974, is 1.

Now, the common factors can be found like this.

721:7x 103

547:547

891:3x 3x 3x 3x 11

341:11x 31

974:2x 487

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 = 116711494685478/(1x11)

LCM = 116711494685478/11

LCM = 10610135880498

Thus, we can understand that the LCM of 721,547,891,341,974 is 10610135880498.
