Calculate the LCM of 682,864,721

Given numbers are 682,864,721

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

The LCM of 682,864,721 is 212423904.

Find LCM of 682,864,721 with Prime Factorization


2 682, 864, 721
341, 432, 721

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

2 x 341 x 432 x 721 = 212423904

Therefore, the lowest common multiple of 682,864,721 is 212423904.

LCM Formula to Find Lowest Common Multiple of 682,864,721

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.

682 x 864 x 721 = 424847808

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.

682 : 1, 2, 11, 22, 31, 62, 341, 682

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,864,721, is 1.

Now, the common factors can be found like this.

682:2x 11x 31

864:2x 2x 2x 2x 2x 3x 3x 3

721:7x 103

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

2 = 2

Therefore, the value for common factors is 2.

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 = 424847808/(1x2)

LCM = 424847808/2

LCM = 212423904

Thus, we can understand that the LCM of 682,864,721 is 212423904.
