Find LCM of 650,153,221,909,945 with Prime Factorization
| 3 | 650, 153, 221, 909, 945 |
| 3 | 650, 51, 221, 303, 315 |
| 5 | 650, 17, 221, 101, 105 |
| 13 | 130, 17, 221, 101, 21 |
| 17 | 10, 17, 17, 101, 21 |
| 10, 1, 1, 101, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 17 x 10 x 1 x 1 x 101 x 21 = 210933450
Therefore, the lowest common multiple of 650,153,221,909,945 is 210933450.
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.
650 x 153 x 221 x 909 x 945 = 18879598442250
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.
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
153 : 1, 3, 9, 17, 51, 153
221 : 1, 13, 17, 221
909 : 1, 3, 9, 101, 303, 909
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,153,221,909,945, is 1.
Now, the common factors can be found like this.
650:2x 5x 5x 13
153:3x 3x 17
221:13x 17
909:3x 3x 101
945:3x 3x 3x 5x 7
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 3x 3x 5x 13x 17 = 89505
Therefore, the value for common factors is 89505.
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 = 18879598442250/(1x89505)
LCM = 18879598442250/89505
LCM = 210933450
Thus, we can understand that the LCM of 650,153,221,909,945 is 210933450.
