Calculate the LCM of 876,721,206,442

Given numbers are 876,721,206,442

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

The LCM of 876,721,206,442 is 139582716.

Find LCM of 876,721,206,442 with Prime Factorization


2 876, 721, 206, 442
103 438, 721, 103, 221
438, 7, 1, 221

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

2 x 103 x 438 x 7 x 1 x 221 = 139582716

Therefore, the lowest common multiple of 876,721,206,442 is 139582716.

LCM Formula to Find Lowest Common Multiple of 876,721,206,442

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.

876 x 721 x 206 x 442 = 57508078992

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.

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

721 : 1, 7, 103, 721

206 : 1, 2, 103, 206

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 876,721,206,442, is 1.

Now, the common factors can be found like this.

876:2x 2x 3x 73

721:7x 103

206:2x 103

442:2x 13x 17

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 103 = 412

Therefore, the value for common factors is 412.

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 = 57508078992/(1x412)

LCM = 57508078992/412

LCM = 139582716

Thus, we can understand that the LCM of 876,721,206,442 is 139582716.
