Given numbers are 802,393,921,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,393,921,345 is 11127641730.
Find LCM of 802,393,921,345 with Prime Factorization
3 | 802, 393, 921, 345 |
802, 131, 307, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 802 x 131 x 307 x 115 = 11127641730
Therefore, the lowest common multiple of 802,393,921,345 is 11127641730.
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.
802 x 393 x 921 x 345 = 100148775570
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.
802 : 1, 2, 401, 802
393 : 1, 3, 131, 393
921 : 1, 3, 307, 921
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,393,921,345, is 1.
Now, the common factors can be found like this.
802:2x 401
393:3x 131
921:3x 307
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 100148775570/(1x9)
LCM = 100148775570/9
LCM = 11127641730
Thus, we can understand that the LCM of 802,393,921,345 is 11127641730.
