Given numbers are 355,663,658,721

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

The LCM of 355,663,658,721 is 15951627510.

Find LCM of 355,663,658,721 with Prime Factorization

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

7 x 355 x 663 x 94 x 103 = 15951627510

Therefore, the lowest common multiple of 355,663,658,721 is 15951627510.

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.

355 x 663 x 658 x 721 = 111661392570

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.

355 : 1, 5, 71, 355

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

658 : 1, 2, 7, 14, 47, 94, 329, 658

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,663,658,721, is 1.

Now, the common factors can be found like this.

355:5x 71

663:3x 13x 17

658:2x 7x 47

721:7x 103

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

7 = 7

Therefore, the value for common factors is 7.

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 = 111661392570/(1x7)

LCM = 111661392570/7

LCM = 15951627510

Thus, we can understand that the LCM of 355,663,658,721 is 15951627510.
