Find LCM of 719,748,642,968,405 with Prime Factorization
| 2 | 719, 748, 642, 968, 405 |
| 2 | 719, 374, 321, 484, 405 |
| 3 | 719, 187, 321, 242, 405 |
| 11 | 719, 187, 107, 242, 135 |
| 719, 17, 107, 22, 135 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 719 x 17 x 107 x 22 x 135 = 512733826440
Therefore, the lowest common multiple of 719,748,642,968,405 is 512733826440.
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.
719 x 748 x 642 x 968 x 405 = 135361730180160
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.
719 : 1, 719
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
642 : 1, 2, 3, 6, 107, 214, 321, 642
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,748,642,968,405, is 1.
Now, the common factors can be found like this.
719:719
748:2x 2x 11x 17
642:2x 3x 107
968:2x 2x 2x 11x 11
405:3x 3x 3x 3x 5
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 135361730180160/(1x264)
LCM = 135361730180160/264
LCM = 512733826440
Thus, we can understand that the LCM of 719,748,642,968,405 is 512733826440.
