Calculate the LCM of 742,665,910,169

Given numbers are 742,665,910,169

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

The LCM of 742,665,910,169 is 11912810.

Find LCM of 742,665,910,169 with Prime Factorization


2 742, 665, 910, 169
5 371, 665, 455, 169
7 371, 133, 91, 169
13 53, 19, 13, 169
53, 19, 1, 13

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

2 x 5 x 7 x 13 x 53 x 19 x 1 x 13 = 11912810

Therefore, the lowest common multiple of 742,665,910,169 is 11912810.

LCM Formula to Find Lowest Common Multiple of 742,665,910,169

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.

742 x 665 x 910 x 169 = 75884599700

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

665 : 1, 5, 7, 19, 35, 95, 133, 665

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,665,910,169, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

665:5x 7x 19

910:2x 5x 7x 13

169:13x 13

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

2x 5x 7x 7x 13 = 6370

Therefore, the value for common factors is 6370.

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 = 75884599700/(1x6370)

LCM = 75884599700/6370

LCM = 11912810

Thus, we can understand that the LCM of 742,665,910,169 is 11912810.
