Given numbers are 721,618,763,137

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

The LCM of 721,618,763,137 is 64600158.

Find LCM of 721,618,763,137 with Prime Factorization

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

7 x 103 x 1 x 6 x 109 x 137 = 64600158

Therefore, the lowest common multiple of 721,618,763,137 is 64600158.

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 618 x 763 x 137 = 46576713918

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

618 : 1, 2, 3, 6, 103, 206, 309, 618

763 : 1, 7, 109, 763

137 : 1, 137

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,618,763,137, is 1.

Now, the common factors can be found like this.

721:7x 103

618:2x 3x 103

763:7x 109

137:137

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

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 46576713918/(1x721)

LCM = 46576713918/721

LCM = 64600158

Thus, we can understand that the LCM of 721,618,763,137 is 64600158.
