Calculate the LCM of 828,755,668,820

Given numbers are 828,755,668,820

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

The LCM of 828,755,668,820 is 4280333580.

Find LCM of 828,755,668,820 with Prime Factorization


2 828, 755, 668, 820
2 414, 755, 334, 410
5 207, 755, 167, 205
207, 151, 167, 41

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

2 x 2 x 5 x 207 x 151 x 167 x 41 = 4280333580

Therefore, the lowest common multiple of 828,755,668,820 is 4280333580.

LCM Formula to Find Lowest Common Multiple of 828,755,668,820

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.

828 x 755 x 668 x 820 = 342426686400

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.

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

755 : 1, 5, 151, 755

668 : 1, 2, 4, 167, 334, 668

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,755,668,820, is 1.

Now, the common factors can be found like this.

828:2x 2x 3x 3x 23

755:5x 151

668:2x 2x 167

820:2x 2x 5x 41

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 5 = 80

Therefore, the value for common factors is 80.

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 = 342426686400/(1x80)

LCM = 342426686400/80

LCM = 4280333580

Thus, we can understand that the LCM of 828,755,668,820 is 4280333580.
