Calculate the LCM of 409,666,844,639

Given numbers are 409,666,844,639

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

The LCM of 409,666,844,639 is 8161469028.

Find LCM of 409,666,844,639 with Prime Factorization


2 409, 666, 844, 639
3 409, 333, 422, 639
3 409, 111, 422, 213
409, 37, 422, 71

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

2 x 3 x 3 x 409 x 37 x 422 x 71 = 8161469028

Therefore, the lowest common multiple of 409,666,844,639 is 8161469028.

LCM Formula to Find Lowest Common Multiple of 409,666,844,639

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.

409 x 666 x 844 x 639 = 146906442504

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.

409 : 1, 409

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

844 : 1, 2, 4, 211, 422, 844

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,666,844,639, is 1.

Now, the common factors can be found like this.

409:409

666:2x 3x 3x 37

844:2x 2x 211

639:3x 3x 71

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 = 146906442504/(1x18)

LCM = 146906442504/18

LCM = 8161469028

Thus, we can understand that the LCM of 409,666,844,639 is 8161469028.
