Calculate the LCM of 855,742,669,119

Given numbers are 855,742,669,119

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

The LCM of 855,742,669,119 is 2405048310.

Find LCM of 855,742,669,119 with Prime Factorization


3 855, 742, 669, 119
7 285, 742, 223, 119
285, 106, 223, 17

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

3 x 7 x 285 x 106 x 223 x 17 = 2405048310

Therefore, the lowest common multiple of 855,742,669,119 is 2405048310.

LCM Formula to Find Lowest Common Multiple of 855,742,669,119

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.

855 x 742 x 669 x 119 = 50506014510

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.

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

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

669 : 1, 3, 223, 669

119 : 1, 7, 17, 119

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,742,669,119, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

742:2x 7x 53

669:3x 223

119:7x 17

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 50506014510/(1x21)

LCM = 50506014510/21

LCM = 2405048310

Thus, we can understand that the LCM of 855,742,669,119 is 2405048310.
