Calculate the LCM of 783,360,645,985

Given numbers are 783,360,645,985

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

The LCM of 783,360,645,985 is 265311720.

Find LCM of 783,360,645,985 with Prime Factorization


3 783, 360, 645, 985
3 261, 120, 215, 985
5 87, 40, 215, 985
87, 8, 43, 197

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

3 x 3 x 5 x 87 x 8 x 43 x 197 = 265311720

Therefore, the lowest common multiple of 783,360,645,985 is 265311720.

LCM Formula to Find Lowest Common Multiple of 783,360,645,985

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.

783 x 360 x 645 x 985 = 179085411000

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360

645 : 1, 3, 5, 15, 43, 129, 215, 645

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,360,645,985, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

360:2x 2x 2x 3x 3x 5

645:3x 5x 43

985:5x 197

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

3x 3x 3x 5x 5 = 675

Therefore, the value for common factors is 675.

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 = 179085411000/(1x675)

LCM = 179085411000/675

LCM = 265311720

Thus, we can understand that the LCM of 783,360,645,985 is 265311720.
