Given numbers are 743,163,815,121

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

The LCM of 743,163,815,121 is 73270945.

Find LCM of 743,163,815,121 with Prime Factorization

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

163 x 743 x 1 x 5 x 121 = 73270945

Therefore, the lowest common multiple of 743,163,815,121 is 73270945.

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.

743 x 163 x 815 x 121 = 11943164035

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.

743 : 1, 743

163 : 1, 163

815 : 1, 5, 163, 815

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,163,815,121, is 1.

Now, the common factors can be found like this.

743:743

163:163

815:5x 163

121:11x 11

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

163 = 163

Therefore, the value for common factors is 163.

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 = 11943164035/(1x163)

LCM = 11943164035/163

LCM = 73270945

Thus, we can understand that the LCM of 743,163,815,121 is 73270945.
