Calculate the LCM of 979,724,390,605,898

Given numbers are 979,724,390,605,898

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

The LCM of 979,724,390,605,898 is 682644971580.

Find LCM of 979,724,390,605,898 with Prime Factorization


2 979, 724, 390, 605, 898
5 979, 362, 195, 605, 449
11 979, 362, 39, 121, 449
89, 362, 39, 11, 449

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

2 x 5 x 11 x 89 x 362 x 39 x 11 x 449 = 682644971580

Therefore, the lowest common multiple of 979,724,390,605,898 is 682644971580.

LCM Formula to Find Lowest Common Multiple of 979,724,390,605,898

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.

979 x 724 x 390 x 605 x 898 = 150181893747600

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.

979 : 1, 11, 89, 979

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

605 : 1, 5, 11, 55, 121, 605

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,724,390,605,898, is 1.

Now, the common factors can be found like this.

979:11x 89

724:2x 2x 181

390:2x 3x 5x 13

605:5x 11x 11

898:2x 449

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 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 150181893747600/(1x220)

LCM = 150181893747600/220

LCM = 682644971580

Thus, we can understand that the LCM of 979,724,390,605,898 is 682644971580.
