Calculate the LCM of 655,268,655,393

Given numbers are 655,268,655,393

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

The LCM of 655,268,655,393 is 526620.

Find LCM of 655,268,655,393 with Prime Factorization


5 655, 268, 655, 393
131 131, 268, 131, 393
1, 268, 1, 3

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

5 x 131 x 1 x 268 x 1 x 3 = 526620

Therefore, the lowest common multiple of 655,268,655,393 is 526620.

LCM Formula to Find Lowest Common Multiple of 655,268,655,393

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.

655 x 268 x 655 x 393 = 45186629100

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

268 : 1, 2, 4, 67, 134, 268

655 : 1, 5, 131, 655

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,268,655,393, is 1.

Now, the common factors can be found like this.

655:5x 131

268:2x 2x 67

655:5x 131

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.

5x 131x 131 = 85805

Therefore, the value for common factors is 85805.

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 = 45186629100/(1x85805)

LCM = 45186629100/85805

LCM = 526620

Thus, we can understand that the LCM of 655,268,655,393 is 526620.
