Given numbers are 730,481,221,789

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

The LCM of 730,481,221,789 is 4709706690.

Find LCM of 730,481,221,789 with Prime Factorization

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

13 x 730 x 37 x 17 x 789 = 4709706690

Therefore, the lowest common multiple of 730,481,221,789 is 4709706690.

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.

730 x 481 x 221 x 789 = 61226186970

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.

730 : 1, 2, 5, 10, 73, 146, 365, 730

481 : 1, 13, 37, 481

221 : 1, 13, 17, 221

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,481,221,789, is 1.

Now, the common factors can be found like this.

730:2x 5x 73

481:13x 37

221:13x 17

789:3x 263

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

13 = 13

Therefore, the value for common factors is 13.

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 = 61226186970/(1x13)

LCM = 61226186970/13

LCM = 4709706690

Thus, we can understand that the LCM of 730,481,221,789 is 4709706690.
