Calculate the LCM of 431,649,484,721,173

Given numbers are 431,649,484,721,173

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

The LCM of 431,649,484,721,173 is 1535168361188.

Find LCM of 431,649,484,721,173 with Prime Factorization


11 431, 649, 484, 721, 173
431, 59, 44, 721, 173

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

11 x 431 x 59 x 44 x 721 x 173 = 1535168361188

Therefore, the lowest common multiple of 431,649,484,721,173 is 1535168361188.

LCM Formula to Find Lowest Common Multiple of 431,649,484,721,173

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.

431 x 649 x 484 x 721 x 173 = 16886851973068

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.

431 : 1, 431

649 : 1, 11, 59, 649

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

721 : 1, 7, 103, 721

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,649,484,721,173, is 1.

Now, the common factors can be found like this.

431:431

649:11x 59

484:2x 2x 11x 11

721:7x 103

173:173

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

11 = 11

Therefore, the value for common factors is 11.

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 = 16886851973068/(1x11)

LCM = 16886851973068/11

LCM = 1535168361188

Thus, we can understand that the LCM of 431,649,484,721,173 is 1535168361188.
