Calculate the LCM of 561,731,653,743

Given numbers are 561,731,653,743

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

The LCM of 561,731,653,743 is 11703973017.

Find LCM of 561,731,653,743 with Prime Factorization


17 561, 731, 653, 743
33, 43, 653, 743

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

17 x 33 x 43 x 653 x 743 = 11703973017

Therefore, the lowest common multiple of 561,731,653,743 is 11703973017.

LCM Formula to Find Lowest Common Multiple of 561,731,653,743

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.

561 x 731 x 653 x 743 = 198967541289

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

731 : 1, 17, 43, 731

653 : 1, 653

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,731,653,743, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

731:17x 43

653:653

743:743

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

17 = 17

Therefore, the value for common factors is 17.

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 = 198967541289/(1x17)

LCM = 198967541289/17

LCM = 11703973017

Thus, we can understand that the LCM of 561,731,653,743 is 11703973017.
