Given numbers are 623,787,146,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,787,146,438 is 214751838.
Find LCM of 623,787,146,438 with Prime Factorization
| 2 | 623, 787, 146, 438 |
| 73 | 623, 787, 73, 219 |
| 623, 787, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 73 x 623 x 787 x 1 x 3 = 214751838
Therefore, the lowest common multiple of 623,787,146,438 is 214751838.
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.
623 x 787 x 146 x 438 = 31353768348
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.
623 : 1, 7, 89, 623
787 : 1, 787
146 : 1, 2, 73, 146
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,787,146,438, is 1.
Now, the common factors can be found like this.
623:7x 89
787:787
146:2x 73
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 73 = 146
Therefore, the value for common factors is 146.
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 = 31353768348/(1x146)
LCM = 31353768348/146
LCM = 214751838
Thus, we can understand that the LCM of 623,787,146,438 is 214751838.
