Calculate the LCM of 655,333,111,720

Given numbers are 655,333,111,720

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

The LCM of 655,333,111,720 is 3489840.

Find LCM of 655,333,111,720 with Prime Factorization


3 655, 333, 111, 720
3 655, 111, 37, 240
5 655, 37, 37, 80
37 131, 37, 37, 16
131, 1, 1, 16

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

3 x 3 x 5 x 37 x 131 x 1 x 1 x 16 = 3489840

Therefore, the lowest common multiple of 655,333,111,720 is 3489840.

LCM Formula to Find Lowest Common Multiple of 655,333,111,720

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.

655 x 333 x 111 x 720 = 17431750800

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.

655 : 1, 5, 131, 655

333 : 1, 3, 9, 37, 111, 333

111 : 1, 3, 37, 111

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,333,111,720, is 1.

Now, the common factors can be found like this.

655:5x 131

333:3x 3x 37

111:3x 37

720:2x 2x 2x 2x 3x 3x 5

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 37 = 4995

Therefore, the value for common factors is 4995.

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 = 17431750800/(1x4995)

LCM = 17431750800/4995

LCM = 3489840

Thus, we can understand that the LCM of 655,333,111,720 is 3489840.
