Calculate the LCM of 724,855,834,940

Given numbers are 724,855,834,940

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

The LCM of 724,855,834,940 is 4044057660.

Find LCM of 724,855,834,940 with Prime Factorization


2 724, 855, 834, 940
2 362, 855, 417, 470
3 181, 855, 417, 235
5 181, 285, 139, 235
181, 57, 139, 47

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

2 x 2 x 3 x 5 x 181 x 57 x 139 x 47 = 4044057660

Therefore, the lowest common multiple of 724,855,834,940 is 4044057660.

LCM Formula to Find Lowest Common Multiple of 724,855,834,940

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.

724 x 855 x 834 x 940 = 485286919200

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.

724 : 1, 2, 4, 181, 362, 724

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

834 : 1, 2, 3, 6, 139, 278, 417, 834

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,855,834,940, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

855:3x 3x 5x 19

834:2x 3x 139

940:2x 2x 5x 47

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

2x 2x 2x 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 485286919200/(1x120)

LCM = 485286919200/120

LCM = 4044057660

Thus, we can understand that the LCM of 724,855,834,940 is 4044057660.
