Given numbers are 108,674,861,718,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 108,674,861,718,455 is 243749289420.
Find LCM of 108,674,861,718,455 with Prime Factorization
| 2 | 108, 674, 861, 718, 455 |
| 3 | 54, 337, 861, 359, 455 |
| 7 | 18, 337, 287, 359, 455 |
| 18, 337, 41, 359, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 18 x 337 x 41 x 359 x 65 = 243749289420
Therefore, the lowest common multiple of 108,674,861,718,455 is 243749289420.
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.
108 x 674 x 861 x 718 x 455 = 20474940311280
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
674 : 1, 2, 337, 674
861 : 1, 3, 7, 21, 41, 123, 287, 861
718 : 1, 2, 359, 718
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 108,674,861,718,455, is 1.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
674:2x 337
861:3x 7x 41
718:2x 359
455:5x 7x 13
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 20474940311280/(1x84)
LCM = 20474940311280/84
LCM = 243749289420
Thus, we can understand that the LCM of 108,674,861,718,455 is 243749289420.
