Given numbers are 230,661,815,77

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

The LCM of 230,661,815,77 is 1908128530.

Find LCM of 230,661,815,77 with Prime Factorization

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

5 x 46 x 661 x 163 x 77 = 1908128530

Therefore, the lowest common multiple of 230,661,815,77 is 1908128530.

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.

230 x 661 x 815 x 77 = 9540642650

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.

230 : 1, 2, 5, 10, 23, 46, 115, 230

661 : 1, 661

815 : 1, 5, 163, 815

77 : 1, 7, 11, 77

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,661,815,77, is 1.

Now, the common factors can be found like this.

230:2x 5x 23

661:661

815:5x 163

77:7x 11

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

5 = 5

Therefore, the value for common factors is 5.

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 = 9540642650/(1x5)

LCM = 9540642650/5

LCM = 1908128530

Thus, we can understand that the LCM of 230,661,815,77 is 1908128530.
