Given numbers are 169,287,978,807,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,287,978,807,160 is 1020821299680.
Find LCM of 169,287,978,807,160 with Prime Factorization
| 2 | 169, 287, 978, 807, 160 |
| 3 | 169, 287, 489, 807, 80 |
| 169, 287, 163, 269, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 169 x 287 x 163 x 269 x 80 = 1020821299680
Therefore, the lowest common multiple of 169,287,978,807,160 is 1020821299680.
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.
169 x 287 x 978 x 807 x 160 = 6124927798080
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.
169 : 1, 13, 169
287 : 1, 7, 41, 287
978 : 1, 2, 3, 6, 163, 326, 489, 978
807 : 1, 3, 269, 807
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,287,978,807,160, is 1.
Now, the common factors can be found like this.
169:13x 13
287:7x 41
978:2x 3x 163
807:3x 269
160:2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 6124927798080/(1x6)
LCM = 6124927798080/6
LCM = 1020821299680
Thus, we can understand that the LCM of 169,287,978,807,160 is 1020821299680.
