Find LCM of 380,394,312,888,920 with Prime Factorization
| 2 | 380, 394, 312, 888, 920 |
| 2 | 190, 197, 156, 444, 460 |
| 2 | 95, 197, 78, 222, 230 |
| 3 | 95, 197, 39, 111, 115 |
| 5 | 95, 197, 13, 37, 115 |
| 19, 197, 13, 37, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 19 x 197 x 13 x 37 x 23 = 4969057080
Therefore, the lowest common multiple of 380,394,312,888,920 is 4969057080.
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.
380 x 394 x 312 x 888 x 920 = 38162358374400
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
394 : 1, 2, 197, 394
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,394,312,888,920, is 2.
Now, the common factors can be found like this.
380:2x 2x 5x 19
394:2x 197
312:2x 2x 2x 3x 13
888:2x 2x 2x 3x 37
920:2x 2x 2x 5x 23
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 2x 2x 3x 5 = 3840
Therefore, the value for common factors is 3840.
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 = 38162358374400/(2x3840)
LCM = 38162358374400/7680
LCM = 4969057080
Thus, we can understand that the LCM of 380,394,312,888,920 is 4969057080.
