Find LCM of 646,565,621,869,135 with Prime Factorization
| 3 | 646, 565, 621, 869, 135 |
| 3 | 646, 565, 207, 869, 45 |
| 3 | 646, 565, 69, 869, 15 |
| 5 | 646, 565, 23, 869, 5 |
| 646, 113, 23, 869, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 646 x 113 x 23 x 869 x 1 = 196966488510
Therefore, the lowest common multiple of 646,565,621,869,135 is 196966488510.
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.
646 x 565 x 621 x 869 x 135 = 26590475948850
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
565 : 1, 5, 113, 565
621 : 1, 3, 9, 23, 27, 69, 207, 621
869 : 1, 11, 79, 869
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,565,621,869,135, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
565:5x 113
621:3x 3x 3x 23
869:11x 79
135:3x 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.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 26590475948850/(1x135)
LCM = 26590475948850/135
LCM = 196966488510
Thus, we can understand that the LCM of 646,565,621,869,135 is 196966488510.
