Calculate the LCM of 867,121,859,209

Given numbers are 867,121,859,209

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

The LCM of 867,121,859,209 is 1712187147.

Find LCM of 867,121,859,209 with Prime Factorization


11 867, 121, 859, 209
867, 11, 859, 19

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

11 x 867 x 11 x 859 x 19 = 1712187147

Therefore, the lowest common multiple of 867,121,859,209 is 1712187147.

LCM Formula to Find Lowest Common Multiple of 867,121,859,209

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 121 x 859 x 209 = 18834058617

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

121 : 1, 11, 121

859 : 1, 859

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,121,859,209, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

121:11x 11

859:859

209:11x 19

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

11 = 11

Therefore, the value for common factors is 11.

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 = 18834058617/(1x11)

LCM = 18834058617/11

LCM = 1712187147

Thus, we can understand that the LCM of 867,121,859,209 is 1712187147.
