Given numbers are 814,633,722,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,633,722,645 is 39992060130.
Find LCM of 814,633,722,645 with Prime Factorization
| 2 | 814, 633, 722, 645 |
| 3 | 407, 633, 361, 645 |
| 407, 211, 361, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 407 x 211 x 361 x 215 = 39992060130
Therefore, the lowest common multiple of 814,633,722,645 is 39992060130.
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.
814 x 633 x 722 x 645 = 239952360780
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
633 : 1, 3, 211, 633
722 : 1, 2, 19, 38, 361, 722
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,633,722,645, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
633:3x 211
722:2x 19x 19
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 239952360780/(1x6)
LCM = 239952360780/6
LCM = 39992060130
Thus, we can understand that the LCM of 814,633,722,645 is 39992060130.
