Find LCM of 282,705,140,351,636 with Prime Factorization
| 2 | 282, 705, 140, 351, 636 |
| 2 | 141, 705, 70, 351, 318 |
| 3 | 141, 705, 35, 351, 159 |
| 5 | 47, 235, 35, 117, 53 |
| 47 | 47, 47, 7, 117, 53 |
| 1, 1, 7, 117, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 47 x 1 x 1 x 7 x 117 x 53 = 122407740
Therefore, the lowest common multiple of 282,705,140,351,636 is 122407740.
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.
282 x 705 x 140 x 351 x 636 = 6213416882400
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
705 : 1, 3, 5, 15, 47, 141, 235, 705
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
351 : 1, 3, 9, 13, 27, 39, 117, 351
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,705,140,351,636, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
705:3x 5x 47
140:2x 2x 5x 7
351:3x 3x 3x 13
636:2x 2x 3x 53
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 3x 3x 3x 5x 47 = 50760
Therefore, the value for common factors is 50760.
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 = 6213416882400/(1x50760)
LCM = 6213416882400/50760
LCM = 122407740
Thus, we can understand that the LCM of 282,705,140,351,636 is 122407740.
