Given numbers are 131,455,765,782,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,455,765,782,665 is 7970499810.
Find LCM of 131,455,765,782,665 with Prime Factorization
| 5 | 131, 455, 765, 782, 665 |
| 7 | 131, 91, 153, 782, 133 |
| 17 | 131, 13, 153, 782, 19 |
| 131, 13, 9, 46, 19 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 17 x 131 x 13 x 9 x 46 x 19 = 7970499810
Therefore, the lowest common multiple of 131,455,765,782,665 is 7970499810.
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.
131 x 455 x 765 x 782 x 665 = 23712236934750
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.
131 : 1, 131
455 : 1, 5, 7, 13, 35, 65, 91, 455
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
782 : 1, 2, 17, 23, 34, 46, 391, 782
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,455,765,782,665, is 1.
Now, the common factors can be found like this.
131:131
455:5x 7x 13
765:3x 3x 5x 17
782:2x 17x 23
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 17 = 2975
Therefore, the value for common factors is 2975.
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 = 23712236934750/(1x2975)
LCM = 23712236934750/2975
LCM = 7970499810
Thus, we can understand that the LCM of 131,455,765,782,665 is 7970499810.
