Calculate the LCM of 960,391,801,644

Given numbers are 960,391,801,644

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

The LCM of 960,391,801,644 is 701547840.

Find LCM of 960,391,801,644 with Prime Factorization


2 960, 391, 801, 644
2 480, 391, 801, 322
3 240, 391, 801, 161
23 80, 391, 267, 161
80, 17, 267, 7

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

2 x 2 x 3 x 23 x 80 x 17 x 267 x 7 = 701547840

Therefore, the lowest common multiple of 960,391,801,644 is 701547840.

LCM Formula to Find Lowest Common Multiple of 960,391,801,644

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.

960 x 391 x 801 x 644 = 193627203840

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.

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

391 : 1, 17, 23, 391

801 : 1, 3, 9, 89, 267, 801

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,391,801,644, is 1.

Now, the common factors can be found like this.

960:2x 2x 2x 2x 2x 2x 3x 5

391:17x 23

801:3x 3x 89

644:2x 2x 7x 23

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 23 = 276

Therefore, the value for common factors is 276.

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 = 193627203840/(1x276)

LCM = 193627203840/276

LCM = 701547840

Thus, we can understand that the LCM of 960,391,801,644 is 701547840.
