Calculate the LCM of 646,996,724

Given numbers are 646,996,724

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

The LCM of 646,996,724 is 58229148.

Find LCM of 646,996,724 with Prime Factorization


2 646, 996, 724
2 323, 498, 362
323, 249, 181

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

2 x 2 x 323 x 249 x 181 = 58229148

Therefore, the lowest common multiple of 646,996,724 is 58229148.

LCM Formula to Find Lowest Common Multiple of 646,996,724

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.

646 x 996 x 724 = 465833184

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,996,724, is 2.

Now, the common factors can be found like this.

646:2x 17x 19

996:2x 2x 3x 83

724:2x 2x 181

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 465833184/(2x4)

LCM = 465833184/8

LCM = 58229148

Thus, we can understand that the LCM of 646,996,724 is 58229148.
