Given numbers are 633,161,407,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 633,161,407,819 is 1617665049.
Find LCM of 633,161,407,819 with Prime Factorization
| 3 | 633, 161, 407, 819 |
| 7 | 211, 161, 407, 273 |
| 211, 23, 407, 39 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 211 x 23 x 407 x 39 = 1617665049
Therefore, the lowest common multiple of 633,161,407,819 is 1617665049.
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.
633 x 161 x 407 x 819 = 33970966029
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.
633 : 1, 3, 211, 633
161 : 1, 7, 23, 161
407 : 1, 11, 37, 407
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 633,161,407,819, is 1.
Now, the common factors can be found like this.
633:3x 211
161:7x 23
407:11x 37
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 33970966029/(1x21)
LCM = 33970966029/21
LCM = 1617665049
Thus, we can understand that the LCM of 633,161,407,819 is 1617665049.
