Calculate the LCM of 121,431,703,605

Given numbers are 121,431,703,605

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

The LCM of 121,431,703,605 is 183310765.

Find LCM of 121,431,703,605 with Prime Factorization


11 121, 431, 703, 605
11 11, 431, 703, 55
1, 431, 703, 5

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

11 x 11 x 1 x 431 x 703 x 5 = 183310765

Therefore, the lowest common multiple of 121,431,703,605 is 183310765.

LCM Formula to Find Lowest Common Multiple of 121,431,703,605

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 431 x 703 x 605 = 22180602565

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

431 : 1, 431

703 : 1, 19, 37, 703

605 : 1, 5, 11, 55, 121, 605

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,431,703,605, is 1.

Now, the common factors can be found like this.

121:11x 11

431:431

703:19x 37

605:5x 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.

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 22180602565/(1x121)

LCM = 22180602565/121

LCM = 183310765

Thus, we can understand that the LCM of 121,431,703,605 is 183310765.
