Find LCM of 721,676,396,968,741 with Prime Factorization
| 2 | 721, 676, 396, 968, 741 |
| 2 | 721, 338, 198, 484, 741 |
| 3 | 721, 169, 99, 242, 741 |
| 11 | 721, 169, 33, 242, 247 |
| 13 | 721, 169, 3, 22, 247 |
| 721, 13, 3, 22, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 721 x 13 x 3 x 22 x 19 = 20169421272
Therefore, the lowest common multiple of 721,676,396,968,741 is 20169421272.
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 676 x 396 x 968 x 741 = 138442907611008
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
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,676,396,968,741, is 1.
Now, the common factors can be found like this.
721:7x 103
676:2x 2x 13x 13
396:2x 2x 3x 3x 11
968:2x 2x 2x 11x 11
741:3x 13x 19
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 2x 3x 11x 13 = 6864
Therefore, the value for common factors is 6864.
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 = 138442907611008/(1x6864)
LCM = 138442907611008/6864
LCM = 20169421272
Thus, we can understand that the LCM of 721,676,396,968,741 is 20169421272.
