Calculate the LCM of 981,443,987,801,707

Given numbers are 981,443,987,801,707

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

The LCM of 981,443,987,801,707 is 1285227507123.

Find LCM of 981,443,987,801,707 with Prime Factorization


3 981, 443, 987, 801, 707
3 327, 443, 329, 267, 707
7 109, 443, 329, 89, 707
109, 443, 47, 89, 101

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

3 x 3 x 7 x 109 x 443 x 47 x 89 x 101 = 1285227507123

Therefore, the lowest common multiple of 981,443,987,801,707 is 1285227507123.

LCM Formula to Find Lowest Common Multiple of 981,443,987,801,707

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.

981 x 443 x 987 x 801 x 707 = 242907998846247

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.

981 : 1, 3, 9, 109, 327, 981

443 : 1, 443

987 : 1, 3, 7, 21, 47, 141, 329, 987

801 : 1, 3, 9, 89, 267, 801

707 : 1, 7, 101, 707

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,443,987,801,707, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

443:443

987:3x 7x 47

801:3x 3x 89

707:7x 101

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

3x 3x 3x 7 = 189

Therefore, the value for common factors is 189.

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 = 242907998846247/(1x189)

LCM = 242907998846247/189

LCM = 1285227507123

Thus, we can understand that the LCM of 981,443,987,801,707 is 1285227507123.
