Calculate the LCM of 931,547,789,898,620

Given numbers are 931,547,789,898,620

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

The LCM of 931,547,789,898,620 is 111854134327740.

Find LCM of 931,547,789,898,620 with Prime Factorization


2 931, 547, 789, 898, 620
931, 547, 789, 449, 310

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

2 x 931 x 547 x 789 x 449 x 310 = 111854134327740

Therefore, the lowest common multiple of 931,547,789,898,620 is 111854134327740.

LCM Formula to Find Lowest Common Multiple of 931,547,789,898,620

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.

931 x 547 x 789 x 898 x 620 = 223708268655480

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.

931 : 1, 7, 19, 49, 133, 931

547 : 1, 547

789 : 1, 3, 263, 789

898 : 1, 2, 449, 898

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,547,789,898,620, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

547:547

789:3x 263

898:2x 449

620:2x 2x 5x 31

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

2 = 2

Therefore, the value for common factors is 2.

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 = 223708268655480/(1x2)

LCM = 223708268655480/2

LCM = 111854134327740

Thus, we can understand that the LCM of 931,547,789,898,620 is 111854134327740.
