Calculate the LCM of 393,946,396,722

Given numbers are 393,946,396,722

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

The LCM of 393,946,396,722 is 805271148.

Find LCM of 393,946,396,722 with Prime Factorization


2 393, 946, 396, 722
3 393, 473, 198, 361
11 131, 473, 66, 361
131, 43, 6, 361

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

2 x 3 x 11 x 131 x 43 x 6 x 361 = 805271148

Therefore, the lowest common multiple of 393,946,396,722 is 805271148.

LCM Formula to Find Lowest Common Multiple of 393,946,396,722

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.

393 x 946 x 396 x 722 = 106295791536

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.

393 : 1, 3, 131, 393

946 : 1, 2, 11, 22, 43, 86, 473, 946

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,946,396,722, is 1.

Now, the common factors can be found like this.

393:3x 131

946:2x 11x 43

396:2x 2x 3x 3x 11

722:2x 19x 19

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 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 106295791536/(1x132)

LCM = 106295791536/132

LCM = 805271148

Thus, we can understand that the LCM of 393,946,396,722 is 805271148.
