Find LCM of 318,434,956,440,840 with Prime Factorization
| 2 | 318, 434, 956, 440, 840 |
| 2 | 159, 217, 478, 220, 420 |
| 2 | 159, 217, 239, 110, 210 |
| 3 | 159, 217, 239, 55, 105 |
| 5 | 53, 217, 239, 55, 35 |
| 7 | 53, 217, 239, 11, 7 |
| 53, 31, 239, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 53 x 31 x 239 x 11 x 1 = 3628335480
Therefore, the lowest common multiple of 318,434,956,440,840 is 3628335480.
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.
318 x 434 x 956 x 440 x 840 = 48764828851200
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
434 : 1, 2, 7, 14, 31, 62, 217, 434
956 : 1, 2, 4, 239, 478, 956
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,434,956,440,840, is 2.
Now, the common factors can be found like this.
318:2x 3x 53
434:2x 7x 31
956:2x 2x 239
440:2x 2x 2x 5x 11
840:2x 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 5x 7 = 6720
Therefore, the value for common factors is 6720.
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 = 48764828851200/(2x6720)
LCM = 48764828851200/13440
LCM = 3628335480
Thus, we can understand that the LCM of 318,434,956,440,840 is 3628335480.
