Find LCM of 338,330,720,274,912 with Prime Factorization
| 2 | 338, 330, 720, 274, 912 |
| 2 | 169, 165, 360, 137, 456 |
| 2 | 169, 165, 180, 137, 228 |
| 2 | 169, 165, 90, 137, 114 |
| 3 | 169, 165, 45, 137, 57 |
| 5 | 169, 55, 15, 137, 19 |
| 169, 11, 3, 137, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 169 x 11 x 3 x 137 x 19 = 3484063440
Therefore, the lowest common multiple of 338,330,720,274,912 is 3484063440.
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.
338 x 330 x 720 x 274 x 912 = 20068205414400
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.
338 : 1, 2, 13, 26, 169, 338
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
274 : 1, 2, 137, 274
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,330,720,274,912, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
330:2x 3x 5x 11
720:2x 2x 2x 2x 3x 3x 5
274:2x 137
912:2x 2x 2x 2x 3x 19
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 5 = 2880
Therefore, the value for common factors is 2880.
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 = 20068205414400/(2x2880)
LCM = 20068205414400/5760
LCM = 3484063440
Thus, we can understand that the LCM of 338,330,720,274,912 is 3484063440.
