The LCM of 253,969,640,506,860 is 6746720640.
Find LCM of 253,969,640,506,860 with Prime Factorization
| 2 | 253, 969, 640, 506, 860 |
| 2 | 253, 969, 320, 253, 430 |
| 5 | 253, 969, 160, 253, 215 |
| 11 | 253, 969, 32, 253, 43 |
| 23 | 23, 969, 32, 23, 43 |
| 1, 969, 32, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 23 x 1 x 969 x 32 x 1 x 43 = 6746720640
Therefore, the lowest common multiple of 253,969,640,506,860 is 6746720640.
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.
253 x 969 x 640 x 506 x 860 = 68276812876800
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.
253 : 1, 11, 23, 253
969 : 1, 3, 17, 19, 51, 57, 323, 969
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
506 : 1, 2, 11, 22, 23, 46, 253, 506
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,969,640,506,860, is 1.
Now, the common factors can be found like this.
253:11x 23
969:3x 17x 19
640:2x 2x 2x 2x 2x 2x 2x 5
506:2x 11x 23
860:2x 2x 5x 43
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 5x 11x 23 = 10120
Therefore, the value for common factors is 10120.
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 = 68276812876800/(1x10120)
LCM = 68276812876800/10120
LCM = 6746720640
Thus, we can understand that the LCM of 253,969,640,506,860 is 6746720640.
