Calculate the LCM of 228,897,640,831

Given numbers are 228,897,640,831

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

The LCM of 228,897,640,831 is 3021383040.

Find LCM of 228,897,640,831 with Prime Factorization


2 228, 897, 640, 831
2 114, 897, 320, 831
3 57, 897, 160, 831
19, 299, 160, 277

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

2 x 2 x 3 x 19 x 299 x 160 x 277 = 3021383040

Therefore, the lowest common multiple of 228,897,640,831 is 3021383040.

LCM Formula to Find Lowest Common Multiple of 228,897,640,831

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.

228 x 897 x 640 x 831 = 108769789440

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.

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

897 : 1, 3, 13, 23, 39, 69, 299, 897

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

831 : 1, 3, 277, 831

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,897,640,831, is 1.

Now, the common factors can be found like this.

228:2x 2x 3x 19

897:3x 13x 23

640:2x 2x 2x 2x 2x 2x 2x 5

831:3x 277

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 108769789440/(1x36)

LCM = 108769789440/36

LCM = 3021383040

Thus, we can understand that the LCM of 228,897,640,831 is 3021383040.
