Calculate the LCM of 908,408,435,620

Given numbers are 908,408,435,620

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

The LCM of 908,408,435,620 is 416308920.

Find LCM of 908,408,435,620 with Prime Factorization


2 908, 408, 435, 620
2 454, 204, 435, 310
3 227, 102, 435, 155
5 227, 34, 145, 155
227, 34, 29, 31

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

2 x 2 x 3 x 5 x 227 x 34 x 29 x 31 = 416308920

Therefore, the lowest common multiple of 908,408,435,620 is 416308920.

LCM Formula to Find Lowest Common Multiple of 908,408,435,620

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.

908 x 408 x 435 x 620 = 99914140800

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.

908 : 1, 2, 4, 227, 454, 908

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

435 : 1, 3, 5, 15, 29, 87, 145, 435

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,408,435,620, is 1.

Now, the common factors can be found like this.

908:2x 2x 227

408:2x 2x 2x 3x 17

435:3x 5x 29

620:2x 2x 5x 31

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 2x 2x 3x 5 = 240

Therefore, the value for common factors is 240.

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 = 99914140800/(1x240)

LCM = 99914140800/240

LCM = 416308920

Thus, we can understand that the LCM of 908,408,435,620 is 416308920.
