Calculate the LCM of 551,918,638,808

Given numbers are 551,918,638,808

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

The LCM of 551,918,638,808 is 2247855192.

Find LCM of 551,918,638,808 with Prime Factorization


2 551, 918, 638, 808
29 551, 459, 319, 404
19, 459, 11, 404

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

2 x 29 x 19 x 459 x 11 x 404 = 2247855192

Therefore, the lowest common multiple of 551,918,638,808 is 2247855192.

LCM Formula to Find Lowest Common Multiple of 551,918,638,808

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.

551 x 918 x 638 x 808 = 260751202272

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.

551 : 1, 19, 29, 551

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

638 : 1, 2, 11, 22, 29, 58, 319, 638

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,918,638,808, is 1.

Now, the common factors can be found like this.

551:19x 29

918:2x 3x 3x 3x 17

638:2x 11x 29

808:2x 2x 2x 101

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

2x 2x 29 = 116

Therefore, the value for common factors is 116.

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 = 260751202272/(1x116)

LCM = 260751202272/116

LCM = 2247855192

Thus, we can understand that the LCM of 551,918,638,808 is 2247855192.
