Given numbers are 203,915,869,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,915,869,655 is 21145025055.
Find LCM of 203,915,869,655 with Prime Factorization
| 5 | 203, 915, 869, 655 |
| 203, 183, 869, 131 |
Multiply the prime numbers at the bottom and the left side.
5 x 203 x 183 x 869 x 131 = 21145025055
Therefore, the lowest common multiple of 203,915,869,655 is 21145025055.
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.
203 x 915 x 869 x 655 = 105725125275
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.
203 : 1, 7, 29, 203
915 : 1, 3, 5, 15, 61, 183, 305, 915
869 : 1, 11, 79, 869
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,915,869,655, is 1.
Now, the common factors can be found like this.
203:7x 29
915:3x 5x 61
869:11x 79
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 105725125275/(1x5)
LCM = 105725125275/5
LCM = 21145025055
Thus, we can understand that the LCM of 203,915,869,655 is 21145025055.
