Given numbers are 124,992,242,419,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 124,992,242,419,810 is 20368830240.
Find LCM of 124,992,242,419,810 with Prime Factorization
| 2 | 124, 992, 242, 419, 810 |
| 2 | 62, 496, 121, 419, 405 |
| 31 | 31, 248, 121, 419, 405 |
| 1, 8, 121, 419, 405 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 1 x 8 x 121 x 419 x 405 = 20368830240
Therefore, the lowest common multiple of 124,992,242,419,810 is 20368830240.
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.
124 x 992 x 242 x 419 x 810 = 10102939799040
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.
124 : 1, 2, 4, 31, 62, 124
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
242 : 1, 2, 11, 22, 121, 242
419 : 1, 419
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,992,242,419,810, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
992:2x 2x 2x 2x 2x 31
242:2x 11x 11
419:419
810:2x 3x 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.
2x 2x 2x 2x 31 = 496
Therefore, the value for common factors is 496.
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 = 10102939799040/(1x496)
LCM = 10102939799040/496
LCM = 20368830240
Thus, we can understand that the LCM of 124,992,242,419,810 is 20368830240.
