Given numbers are 887,130,686,670,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 887,130,686,670,121 is 320642632310.
Find LCM of 887,130,686,670,121 with Prime Factorization
| 2 | 887, 130, 686, 670, 121 |
| 5 | 887, 65, 343, 335, 121 |
| 887, 13, 343, 67, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 887 x 13 x 343 x 67 x 121 = 320642632310
Therefore, the lowest common multiple of 887,130,686,670,121 is 320642632310.
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.
887 x 130 x 686 x 670 x 121 = 6412852646200
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.
887 : 1, 887
130 : 1, 2, 5, 10, 13, 26, 65, 130
686 : 1, 2, 7, 14, 49, 98, 343, 686
670 : 1, 2, 5, 10, 67, 134, 335, 670
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 887,130,686,670,121, is 1.
Now, the common factors can be found like this.
887:887
130:2x 5x 13
686:2x 7x 7x 7
670:2x 5x 67
121:11x 11
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 5 = 20
Therefore, the value for common factors is 20.
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 = 6412852646200/(1x20)
LCM = 6412852646200/20
LCM = 320642632310
Thus, we can understand that the LCM of 887,130,686,670,121 is 320642632310.
