Calculate the LCM of 441,923,640,994

Given numbers are 441,923,640,994

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

The LCM of 441,923,640,994 is 260507520.

Find LCM of 441,923,640,994 with Prime Factorization


2 441, 923, 640, 994
7 441, 923, 320, 497
71 63, 923, 320, 71
63, 13, 320, 1

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

2 x 7 x 71 x 63 x 13 x 320 x 1 = 260507520

Therefore, the lowest common multiple of 441,923,640,994 is 260507520.

LCM Formula to Find Lowest Common Multiple of 441,923,640,994

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.

441 x 923 x 640 x 994 = 258944474880

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.

441 : 1, 3, 7, 9, 21, 49, 63, 147, 441

923 : 1, 13, 71, 923

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

994 : 1, 2, 7, 14, 71, 142, 497, 994

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,923,640,994, is 1.

Now, the common factors can be found like this.

441:3x 3x 7x 7

923:13x 71

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

994:2x 7x 71

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

2x 7x 71 = 994

Therefore, the value for common factors is 994.

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 = 258944474880/(1x994)

LCM = 258944474880/994

LCM = 260507520

Thus, we can understand that the LCM of 441,923,640,994 is 260507520.
