Find LCM of 721,762,979,945,254 with Prime Factorization
| 2 | 721, 762, 979, 945, 254 |
| 3 | 721, 381, 979, 945, 127 |
| 7 | 721, 127, 979, 315, 127 |
| 127 | 103, 127, 979, 45, 127 |
| 103, 1, 979, 45, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 127 x 103 x 1 x 979 x 45 x 1 = 24203905110
Therefore, the lowest common multiple of 721,762,979,945,254 is 24203905110.
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.
721 x 762 x 979 x 945 x 254 = 129103629856740
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.
721 : 1, 7, 103, 721
762 : 1, 2, 3, 6, 127, 254, 381, 762
979 : 1, 11, 89, 979
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,762,979,945,254, is 1.
Now, the common factors can be found like this.
721:7x 103
762:2x 3x 127
979:11x 89
945:3x 3x 3x 5x 7
254:2x 127
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 127 = 5334
Therefore, the value for common factors is 5334.
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 = 129103629856740/(1x5334)
LCM = 129103629856740/5334
LCM = 24203905110
Thus, we can understand that the LCM of 721,762,979,945,254 is 24203905110.
