Given numbers are 121,181,565,791

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

The LCM of 121,181,565,791 is 86618455.

Find LCM of 121,181,565,791 with Prime Factorization

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

113 x 121 x 181 x 5 x 7 = 86618455

Therefore, the lowest common multiple of 121,181,565,791 is 86618455.

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.

121 x 181 x 565 x 791 = 9787885415

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.

121 : 1, 11, 121

181 : 1, 181

565 : 1, 5, 113, 565

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,181,565,791, is 1.

Now, the common factors can be found like this.

121:11x 11

181:181

565:5x 113

791:7x 113

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

113 = 113

Therefore, the value for common factors is 113.

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 = 9787885415/(1x113)

LCM = 9787885415/113

LCM = 86618455

Thus, we can understand that the LCM of 121,181,565,791 is 86618455.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 510, 823, 217, 257
