Given numbers are 646,200,845,357,365
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,200,845,357,365 is 16736374200.
Find LCM of 646,200,845,357,365 with Prime Factorization
| 2 | 646, 200, 845, 357, 365 |
| 5 | 323, 100, 845, 357, 365 |
| 17 | 323, 20, 169, 357, 73 |
| 19, 20, 169, 21, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 19 x 20 x 169 x 21 x 73 = 16736374200
Therefore, the lowest common multiple of 646,200,845,357,365 is 16736374200.
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.
646 x 200 x 845 x 357 x 365 = 14225918070000
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
845 : 1, 5, 13, 65, 169, 845
357 : 1, 3, 7, 17, 21, 51, 119, 357
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,200,845,357,365, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
200:2x 2x 2x 5x 5
845:5x 13x 13
357:3x 7x 17
365:5x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 17 = 850
Therefore, the value for common factors is 850.
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 = 14225918070000/(1x850)
LCM = 14225918070000/850
LCM = 16736374200
Thus, we can understand that the LCM of 646,200,845,357,365 is 16736374200.
