Calculate the LCM of 724,665,857,462

Given numbers are 724,665,857,462

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

The LCM of 724,665,857,462 is 13616170260.

Find LCM of 724,665,857,462 with Prime Factorization


2 724, 665, 857, 462
7 362, 665, 857, 231
362, 95, 857, 33

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

2 x 7 x 362 x 95 x 857 x 33 = 13616170260

Therefore, the lowest common multiple of 724,665,857,462 is 13616170260.

LCM Formula to Find Lowest Common Multiple of 724,665,857,462

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.

724 x 665 x 857 x 462 = 190626383640

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.

724 : 1, 2, 4, 181, 362, 724

665 : 1, 5, 7, 19, 35, 95, 133, 665

857 : 1, 857

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,665,857,462, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

665:5x 7x 19

857:857

462:2x 3x 7x 11

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 190626383640/(1x14)

LCM = 190626383640/14

LCM = 13616170260

Thus, we can understand that the LCM of 724,665,857,462 is 13616170260.
