Find LCM of 676,140,991,315,273 with Prime Factorization
| 2 | 676, 140, 991, 315, 273 |
| 2 | 338, 70, 991, 315, 273 |
| 3 | 169, 35, 991, 315, 273 |
| 5 | 169, 35, 991, 105, 91 |
| 7 | 169, 7, 991, 21, 91 |
| 13 | 169, 1, 991, 3, 13 |
| 1, 1, 991, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 1 x 1 x 991 x 3 x 13 = 211023540
Therefore, the lowest common multiple of 676,140,991,315,273 is 211023540.
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.
676 x 140 x 991 x 315 x 273 = 8065319698800
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
991 : 1, 991
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,140,991,315,273, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
140:2x 2x 5x 7
991:991
315:3x 3x 5x 7
273:3x 7x 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 3x 5x 7x 7x 13 = 38220
Therefore, the value for common factors is 38220.
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 = 8065319698800/(1x38220)
LCM = 8065319698800/38220
LCM = 211023540
Thus, we can understand that the LCM of 676,140,991,315,273 is 211023540.
