Find LCM of 265,321,560,336,420 with Prime Factorization
| 2 | 265, 321, 560, 336, 420 |
| 2 | 265, 321, 280, 168, 210 |
| 2 | 265, 321, 140, 84, 105 |
| 2 | 265, 321, 70, 42, 105 |
| 3 | 265, 321, 35, 21, 105 |
| 5 | 265, 107, 35, 7, 35 |
| 7 | 53, 107, 7, 7, 7 |
| 53, 107, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 7 x 53 x 107 x 1 x 1 x 1 = 9527280
Therefore, the lowest common multiple of 265,321,560,336,420 is 9527280.
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.
265 x 321 x 560 x 336 x 420 = 6722448768000
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.
265 : 1, 5, 53, 265
321 : 1, 3, 107, 321
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 265,321,560,336,420, is 1.
Now, the common factors can be found like this.
265:5x 53
321:3x 107
560:2x 2x 2x 2x 5x 7
336:2x 2x 2x 2x 3x 7
420:2x 2x 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.
2x 2x 2x 2x 2x 2x 3x 3x 5x 5x 7x 7 = 705600
Therefore, the value for common factors is 705600.
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 = 6722448768000/(1x705600)
LCM = 6722448768000/705600
LCM = 9527280
Thus, we can understand that the LCM of 265,321,560,336,420 is 9527280.
