Find LCM of 315,661,931,225,889 with Prime Factorization
| 3 | 315, 661, 931, 225, 889 |
| 3 | 105, 661, 931, 75, 889 |
| 5 | 35, 661, 931, 25, 889 |
| 7 | 7, 661, 931, 5, 889 |
| 1, 661, 133, 5, 127 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 1 x 661 x 133 x 5 x 127 = 17584797825
Therefore, the lowest common multiple of 315,661,931,225,889 is 17584797825.
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.
315 x 661 x 931 x 225 x 889 = 38774479204125
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
661 : 1, 661
931 : 1, 7, 19, 49, 133, 931
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,661,931,225,889, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
661:661
931:7x 7x 19
225:3x 3x 5x 5
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7x 7 = 2205
Therefore, the value for common factors is 2205.
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 = 38774479204125/(1x2205)
LCM = 38774479204125/2205
LCM = 17584797825
Thus, we can understand that the LCM of 315,661,931,225,889 is 17584797825.
