Calculate the LCM of 576,691,771,787

Given numbers are 576,691,771,787

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

The LCM of 576,691,771,787 is 80502318144.

Find LCM of 576,691,771,787 with Prime Factorization


3 576, 691, 771, 787
192, 691, 257, 787

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

3 x 192 x 691 x 257 x 787 = 80502318144

Therefore, the lowest common multiple of 576,691,771,787 is 80502318144.

LCM Formula to Find Lowest Common Multiple of 576,691,771,787

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.

576 x 691 x 771 x 787 = 241506954432

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.

576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576

691 : 1, 691

771 : 1, 3, 257, 771

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 576,691,771,787, is 1.

Now, the common factors can be found like this.

576:2x 2x 2x 2x 2x 2x 3x 3

691:691

771:3x 257

787:787

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

3 = 3

Therefore, the value for common factors is 3.

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 = 241506954432/(1x3)

LCM = 241506954432/3

LCM = 80502318144

Thus, we can understand that the LCM of 576,691,771,787 is 80502318144.
