Calculate the LCM of 669,390,873,340

Given numbers are 669,390,873,340

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

The LCM of 669,390,873,340 is 860481180.

Find LCM of 669,390,873,340 with Prime Factorization


2 669, 390, 873, 340
3 669, 195, 873, 170
5 223, 65, 291, 170
223, 13, 291, 34

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

2 x 3 x 5 x 223 x 13 x 291 x 34 = 860481180

Therefore, the lowest common multiple of 669,390,873,340 is 860481180.

LCM Formula to Find Lowest Common Multiple of 669,390,873,340

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.

669 x 390 x 873 x 340 = 77443306200

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.

669 : 1, 3, 223, 669

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

873 : 1, 3, 9, 97, 291, 873

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,390,873,340, is 1.

Now, the common factors can be found like this.

669:3x 223

390:2x 3x 5x 13

873:3x 3x 97

340:2x 2x 5x 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 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 77443306200/(1x90)

LCM = 77443306200/90

LCM = 860481180

Thus, we can understand that the LCM of 669,390,873,340 is 860481180.
