Find LCM of 909,360,265,428,321 with Prime Factorization
| 2 | 909, 360, 265, 428, 321 |
| 2 | 909, 180, 265, 214, 321 |
| 3 | 909, 90, 265, 107, 321 |
| 3 | 303, 30, 265, 107, 107 |
| 5 | 101, 10, 265, 107, 107 |
| 107 | 101, 2, 53, 107, 107 |
| 101, 2, 53, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 107 x 101 x 2 x 53 x 1 x 1 = 206197560
Therefore, the lowest common multiple of 909,360,265,428,321 is 206197560.
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.
909 x 360 x 265 x 428 x 321 = 11914095016800
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.
909 : 1, 3, 9, 101, 303, 909
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
265 : 1, 5, 53, 265
428 : 1, 2, 4, 107, 214, 428
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,360,265,428,321, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
360:2x 2x 2x 3x 3x 5
265:5x 53
428:2x 2x 107
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 5x 107 = 57780
Therefore, the value for common factors is 57780.
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 = 11914095016800/(1x57780)
LCM = 11914095016800/57780
LCM = 206197560
Thus, we can understand that the LCM of 909,360,265,428,321 is 206197560.
