The LCM of 438,181,724,627 is 33138204.
Find LCM of 438,181,724,627 with Prime Factorization
| 2 | 438, 181, 724, 627 |
| 3 | 219, 181, 362, 627 |
| 181 | 73, 181, 362, 209 |
| 73, 1, 2, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 181 x 73 x 1 x 2 x 209 = 33138204
Therefore, the lowest common multiple of 438,181,724,627 is 33138204.
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.
438 x 181 x 724 x 627 = 35988089544
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
181 : 1, 181
724 : 1, 2, 4, 181, 362, 724
627 : 1, 3, 11, 19, 33, 57, 209, 627
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,181,724,627, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
181:181
724:2x 2x 181
627:3x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 181 = 1086
Therefore, the value for common factors is 1086.
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 = 35988089544/(1x1086)
LCM = 35988089544/1086
LCM = 33138204
Thus, we can understand that the LCM of 438,181,724,627 is 33138204.
