Calculate the LCM of 340,245,646,708

Given numbers are 340,245,646,708

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

The LCM of 340,245,646,708 is 56027580.

Find LCM of 340,245,646,708 with Prime Factorization


2 340, 245, 646, 708
2 170, 245, 323, 354
5 85, 245, 323, 177
17 17, 49, 323, 177
1, 49, 19, 177

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

2 x 2 x 5 x 17 x 1 x 49 x 19 x 177 = 56027580

Therefore, the lowest common multiple of 340,245,646,708 is 56027580.

LCM Formula to Find Lowest Common Multiple of 340,245,646,708

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.

340 x 245 x 646 x 708 = 38098754400

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.

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

245 : 1, 5, 7, 35, 49, 245

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

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,245,646,708, is 1.

Now, the common factors can be found like this.

340:2x 2x 5x 17

245:5x 7x 7

646:2x 17x 19

708:2x 2x 3x 59

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 2x 5x 17 = 680

Therefore, the value for common factors is 680.

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 = 38098754400/(1x680)

LCM = 38098754400/680

LCM = 56027580

Thus, we can understand that the LCM of 340,245,646,708 is 56027580.
