Calculate the LCM of 613,976,915,393

Given numbers are 613,976,915,393

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

The LCM of 613,976,915,393 is 1175635920.

Find LCM of 613,976,915,393 with Prime Factorization


3 613, 976, 915, 393
61 613, 976, 305, 131
613, 16, 5, 131

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

3 x 61 x 613 x 16 x 5 x 131 = 1175635920

Therefore, the lowest common multiple of 613,976,915,393 is 1175635920.

LCM Formula to Find Lowest Common Multiple of 613,976,915,393

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.

613 x 976 x 915 x 393 = 215141373360

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.

613 : 1, 613

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

915 : 1, 3, 5, 15, 61, 183, 305, 915

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,976,915,393, is 1.

Now, the common factors can be found like this.

613:613

976:2x 2x 2x 2x 61

915:3x 5x 61

393:3x 131

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

3x 61 = 183

Therefore, the value for common factors is 183.

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 = 215141373360/(1x183)

LCM = 215141373360/183

LCM = 1175635920

Thus, we can understand that the LCM of 613,976,915,393 is 1175635920.
