Given numbers are 560,129,991,108,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 560,129,991,108,790 is 50900376240.
Find LCM of 560,129,991,108,790 with Prime Factorization
| 2 | 560, 129, 991, 108, 790 |
| 2 | 280, 129, 991, 54, 395 |
| 3 | 140, 129, 991, 27, 395 |
| 5 | 140, 43, 991, 9, 395 |
| 28, 43, 991, 9, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 28 x 43 x 991 x 9 x 79 = 50900376240
Therefore, the lowest common multiple of 560,129,991,108,790 is 50900376240.
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.
560 x 129 x 991 x 108 x 790 = 6108045148800
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
129 : 1, 3, 43, 129
991 : 1, 991
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,129,991,108,790, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
129:3x 43
991:991
108:2x 2x 3x 3x 3
790:2x 5x 79
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 6108045148800/(1x120)
LCM = 6108045148800/120
LCM = 50900376240
Thus, we can understand that the LCM of 560,129,991,108,790 is 50900376240.
