Given numbers are 645,801,121,723

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

The LCM of 645,801,121,723 is 5021961615.

Find LCM of 645,801,121,723 with Prime Factorization

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

3 x 215 x 267 x 121 x 241 = 5021961615

Therefore, the lowest common multiple of 645,801,121,723 is 5021961615.

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.

645 x 801 x 121 x 723 = 45197654535

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

801 : 1, 3, 9, 89, 267, 801

121 : 1, 11, 121

723 : 1, 3, 241, 723

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,801,121,723, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

801:3x 3x 89

121:11x 11

723:3x 241

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 45197654535/(1x9)

LCM = 45197654535/9

LCM = 5021961615

Thus, we can understand that the LCM of 645,801,121,723 is 5021961615.
