Given numbers are 791,894,452,254,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,894,452,254,686 is 8801238684.
Find LCM of 791,894,452,254,686 with Prime Factorization
| 2 | 791, 894, 452, 254, 686 |
| 7 | 791, 447, 226, 127, 343 |
| 113 | 113, 447, 226, 127, 49 |
| 1, 447, 2, 127, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 113 x 1 x 447 x 2 x 127 x 49 = 8801238684
Therefore, the lowest common multiple of 791,894,452,254,686 is 8801238684.
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.
791 x 894 x 452 x 254 x 686 = 55694238392352
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.
791 : 1, 7, 113, 791
894 : 1, 2, 3, 6, 149, 298, 447, 894
452 : 1, 2, 4, 113, 226, 452
254 : 1, 2, 127, 254
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,894,452,254,686, is 1.
Now, the common factors can be found like this.
791:7x 113
894:2x 3x 149
452:2x 2x 113
254:2x 127
686:2x 7x 7x 7
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 7x 113 = 6328
Therefore, the value for common factors is 6328.
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 = 55694238392352/(1x6328)
LCM = 55694238392352/6328
LCM = 8801238684
Thus, we can understand that the LCM of 791,894,452,254,686 is 8801238684.
