Given numbers are 784,203,515,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,203,515,667 is 269307920.
Find LCM of 784,203,515,667 with Prime Factorization
| 7 | 784, 203, 515, 667 |
| 29 | 112, 29, 515, 667 |
| 112, 1, 515, 23 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 112 x 1 x 515 x 23 = 269307920
Therefore, the lowest common multiple of 784,203,515,667 is 269307920.
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.
784 x 203 x 515 x 667 = 54669507760
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
203 : 1, 7, 29, 203
515 : 1, 5, 103, 515
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,203,515,667, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
203:7x 29
515:5x 103
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 29 = 203
Therefore, the value for common factors is 203.
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 = 54669507760/(1x203)
LCM = 54669507760/203
LCM = 269307920
Thus, we can understand that the LCM of 784,203,515,667 is 269307920.
