Calculate the LCM of 156,423,691,721

Given numbers are 156,423,691,721

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

The LCM of 156,423,691,721 is 10958649156.

Find LCM of 156,423,691,721 with Prime Factorization


3 156, 423, 691, 721
52, 141, 691, 721

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

3 x 52 x 141 x 691 x 721 = 10958649156

Therefore, the lowest common multiple of 156,423,691,721 is 10958649156.

LCM Formula to Find Lowest Common Multiple of 156,423,691,721

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.

156 x 423 x 691 x 721 = 32875947468

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.

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

423 : 1, 3, 9, 47, 141, 423

691 : 1, 691

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,423,691,721, is 1.

Now, the common factors can be found like this.

156:2x 2x 3x 13

423:3x 3x 47

691:691

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.

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 = 32875947468/(1x3)

LCM = 32875947468/3

LCM = 10958649156

Thus, we can understand that the LCM of 156,423,691,721 is 10958649156.
