Calculate the LCM of 867,546,646,955

Given numbers are 867,546,646,955

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

The LCM of 867,546,646,955 is 2863172130.

Find LCM of 867,546,646,955 with Prime Factorization


2 867, 546, 646, 955
3 867, 273, 323, 955
17 289, 91, 323, 955
17, 91, 19, 955

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

2 x 3 x 17 x 17 x 91 x 19 x 955 = 2863172130

Therefore, the lowest common multiple of 867,546,646,955 is 2863172130.

LCM Formula to Find Lowest Common Multiple of 867,546,646,955

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.

867 x 546 x 646 x 955 = 292043557260

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.

867 : 1, 3, 17, 51, 289, 867

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

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

955 : 1, 5, 191, 955

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,546,646,955, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

546:2x 3x 7x 13

646:2x 17x 19

955:5x 191

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

2x 3x 17 = 102

Therefore, the value for common factors is 102.

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 = 292043557260/(1x102)

LCM = 292043557260/102

LCM = 2863172130

Thus, we can understand that the LCM of 867,546,646,955 is 2863172130.
