Calculate the LCM of 910,865,420,521

Given numbers are 910,865,420,521

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

The LCM of 910,865,420,521 is 492126180.

Find LCM of 910,865,420,521 with Prime Factorization


2 910, 865, 420, 521
5 455, 865, 210, 521
7 91, 173, 42, 521
13, 173, 6, 521

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

2 x 5 x 7 x 13 x 173 x 6 x 521 = 492126180

Therefore, the lowest common multiple of 910,865,420,521 is 492126180.

LCM Formula to Find Lowest Common Multiple of 910,865,420,521

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.

910 x 865 x 420 x 521 = 172244163000

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.

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

865 : 1, 5, 173, 865

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,865,420,521, is 1.

Now, the common factors can be found like this.

910:2x 5x 7x 13

865:5x 173

420:2x 2x 3x 5x 7

521:521

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

2x 5x 5x 7 = 350

Therefore, the value for common factors is 350.

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 = 172244163000/(1x350)

LCM = 172244163000/350

LCM = 492126180

Thus, we can understand that the LCM of 910,865,420,521 is 492126180.
