Given numbers are 721,529,348,391

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

The LCM of 721,529,348,391 is 2256415644.

Find LCM of 721,529,348,391 with Prime Factorization

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

23 x 721 x 23 x 348 x 17 = 2256415644

Therefore, the lowest common multiple of 721,529,348,391 is 2256415644.

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 529 x 348 x 391 = 51897559812

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

529 : 1, 23, 529

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,529,348,391, is 1.

Now, the common factors can be found like this.

721:7x 103

529:23x 23

348:2x 2x 3x 29

391:17x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 51897559812/(1x23)

LCM = 51897559812/23

LCM = 2256415644

Thus, we can understand that the LCM of 721,529,348,391 is 2256415644.
