Given numbers are 862,747,669,320,268
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,747,669,320,268 is 1539315051840.
Find LCM of 862,747,669,320,268 with Prime Factorization
| 2 | 862, 747, 669, 320, 268 |
| 2 | 431, 747, 669, 160, 134 |
| 3 | 431, 747, 669, 80, 67 |
| 431, 249, 223, 80, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 431 x 249 x 223 x 80 x 67 = 1539315051840
Therefore, the lowest common multiple of 862,747,669,320,268 is 1539315051840.
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.
862 x 747 x 669 x 320 x 268 = 36943561244160
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.
862 : 1, 2, 431, 862
747 : 1, 3, 9, 83, 249, 747
669 : 1, 3, 223, 669
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,747,669,320,268, is 1.
Now, the common factors can be found like this.
862:2x 431
747:3x 3x 83
669:3x 223
320:2x 2x 2x 2x 2x 2x 5
268:2x 2x 67
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 3 = 24
Therefore, the value for common factors is 24.
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 = 36943561244160/(1x24)
LCM = 36943561244160/24
LCM = 1539315051840
Thus, we can understand that the LCM of 862,747,669,320,268 is 1539315051840.
