Given numbers are 721,483,137,437

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

The LCM of 721,483,137,437 is 129496647.

Find LCM of 721,483,137,437 with Prime Factorization

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

7 x 23 x 103 x 3 x 137 x 19 = 129496647

Therefore, the lowest common multiple of 721,483,137,437 is 129496647.

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 483 x 137 x 437 = 20848960167

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

483 : 1, 3, 7, 21, 23, 69, 161, 483

137 : 1, 137

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,483,137,437, is 1.

Now, the common factors can be found like this.

721:7x 103

483:3x 7x 23

137:137

437:19x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 20848960167/(1x161)

LCM = 20848960167/161

LCM = 129496647

Thus, we can understand that the LCM of 721,483,137,437 is 129496647.
