Given numbers are 917,284,428,635,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,284,428,635,305 is 1079381608060.
Find LCM of 917,284,428,635,305 with Prime Factorization
2 | 917, 284, 428, 635, 305 |
2 | 917, 142, 214, 635, 305 |
5 | 917, 71, 107, 635, 305 |
917, 71, 107, 127, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 917 x 71 x 107 x 127 x 61 = 1079381608060
Therefore, the lowest common multiple of 917,284,428,635,305 is 1079381608060.
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.
917 x 284 x 428 x 635 x 305 = 21587632161200
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.
917 : 1, 7, 131, 917
284 : 1, 2, 4, 71, 142, 284
428 : 1, 2, 4, 107, 214, 428
635 : 1, 5, 127, 635
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,284,428,635,305, is 1.
Now, the common factors can be found like this.
917:7x 131
284:2x 2x 71
428:2x 2x 107
635:5x 127
305:5x 61
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 = 21587632161200/(1x20)
LCM = 21587632161200/20
LCM = 1079381608060
Thus, we can understand that the LCM of 917,284,428,635,305 is 1079381608060.
