Find LCM of 756,917,147,994,449 with Prime Factorization
| 2 | 756, 917, 147, 994, 449 |
| 3 | 378, 917, 147, 497, 449 |
| 7 | 126, 917, 49, 497, 449 |
| 18, 131, 7, 71, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 18 x 131 x 7 x 71 x 449 = 22100180508
Therefore, the lowest common multiple of 756,917,147,994,449 is 22100180508.
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.
756 x 917 x 147 x 994 x 449 = 45482171485464
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
917 : 1, 7, 131, 917
147 : 1, 3, 7, 21, 49, 147
994 : 1, 2, 7, 14, 71, 142, 497, 994
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,917,147,994,449, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
917:7x 131
147:3x 7x 7
994:2x 7x 71
449:449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7x 7 = 2058
Therefore, the value for common factors is 2058.
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 = 45482171485464/(1x2058)
LCM = 45482171485464/2058
LCM = 22100180508
Thus, we can understand that the LCM of 756,917,147,994,449 is 22100180508.
