LCM of:

Calculate the LCM of 240,646,780,206

Given numbers are 240,646,780,206

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

The LCM of 240,646,780,206 is 103799280.

Find LCM of 240,646,780,206 with Prime Factorization


2 240, 646, 780, 206
2 120, 323, 390, 103
3 60, 323, 195, 103
5 20, 323, 65, 103
4, 323, 13, 103

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

2 x 2 x 3 x 5 x 4 x 323 x 13 x 103 = 103799280

Therefore, the lowest common multiple of 240,646,780,206 is 103799280.

LCM Formula to Find Lowest Common Multiple of 240,646,780,206

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.

240 x 646 x 780 x 206 = 24911827200

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.

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

206 : 1, 2, 103, 206

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,646,780,206, is 2.

Now, the common factors can be found like this.

240:2x 2x 2x 2x 3x 5

646:2x 17x 19

780:2x 2x 3x 5x 13

206:2x 103

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 24911827200/(2x120)

LCM = 24911827200/240

LCM = 103799280

Thus, we can understand that the LCM of 240,646,780,206 is 103799280.
