Find LCM of 276,705,745,721,968 with Prime Factorization
| 2 | 276, 705, 745, 721, 968 |
| 2 | 138, 705, 745, 721, 484 |
| 3 | 69, 705, 745, 721, 242 |
| 5 | 23, 235, 745, 721, 242 |
| 23, 47, 149, 721, 242 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 47 x 149 x 721 x 242 = 1686218475480
Therefore, the lowest common multiple of 276,705,745,721,968 is 1686218475480.
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.
276 x 705 x 745 x 721 x 968 = 101173108528800
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.
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
705 : 1, 3, 5, 15, 47, 141, 235, 705
745 : 1, 5, 149, 745
721 : 1, 7, 103, 721
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 276,705,745,721,968, is 1.
Now, the common factors can be found like this.
276:2x 2x 3x 23
705:3x 5x 47
745:5x 149
721:7x 103
968:2x 2x 2x 11x 11
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 5 = 60
Therefore, the value for common factors is 60.
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 = 101173108528800/(1x60)
LCM = 101173108528800/60
LCM = 1686218475480
Thus, we can understand that the LCM of 276,705,745,721,968 is 1686218475480.
