Calculate the LCM of 423,982,546,561

Given numbers are 423,982,546,561

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

The LCM of 423,982,546,561 is 7068623562.

Find LCM of 423,982,546,561 with Prime Factorization


2 423, 982, 546, 561
3 423, 491, 273, 561
141, 491, 91, 187

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

2 x 3 x 141 x 491 x 91 x 187 = 7068623562

Therefore, the lowest common multiple of 423,982,546,561 is 7068623562.

LCM Formula to Find Lowest Common Multiple of 423,982,546,561

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.

423 x 982 x 546 x 561 = 127235224116

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.

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

982 : 1, 2, 491, 982

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,982,546,561, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

982:2x 491

546:2x 3x 7x 13

561:3x 11x 17

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 127235224116/(1x18)

LCM = 127235224116/18

LCM = 7068623562

Thus, we can understand that the LCM of 423,982,546,561 is 7068623562.
