Find LCM of 420,296,381,628,975 with Prime Factorization
| 2 | 420, 296, 381, 628, 975 |
| 2 | 210, 148, 381, 314, 975 |
| 3 | 105, 74, 381, 157, 975 |
| 5 | 35, 74, 127, 157, 325 |
| 7, 74, 127, 157, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 74 x 127 x 157 x 65 = 40280767800
Therefore, the lowest common multiple of 420,296,381,628,975 is 40280767800.
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.
420 x 296 x 381 x 628 x 975 = 29002152816000
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.
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
296 : 1, 2, 4, 8, 37, 74, 148, 296
381 : 1, 3, 127, 381
628 : 1, 2, 4, 157, 314, 628
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,296,381,628,975, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
296:2x 2x 2x 37
381:3x 127
628:2x 2x 157
975:3x 5x 5x 13
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 29002152816000/(1x720)
LCM = 29002152816000/720
LCM = 40280767800
Thus, we can understand that the LCM of 420,296,381,628,975 is 40280767800.
