Given numbers are 721,121,693,635

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

The LCM of 721,121,693,635 is 498582315.

Find LCM of 721,121,693,635 with Prime Factorization

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

7 x 11 x 103 x 11 x 9 x 635 = 498582315

Therefore, the lowest common multiple of 721,121,693,635 is 498582315.

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 121 x 693 x 635 = 38390838255

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

121 : 1, 11, 121

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,121,693,635, is 1.

Now, the common factors can be found like this.

721:7x 103

121:11x 11

693:3x 3x 7x 11

635:5x 127

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

7x 11 = 77

Therefore, the value for common factors is 77.

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 = 38390838255/(1x77)

LCM = 38390838255/77

LCM = 498582315

Thus, we can understand that the LCM of 721,121,693,635 is 498582315.
