Given numbers are 169,660,247,403,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,660,247,403,155 is 65697060.
Find LCM of 169,660,247,403,155 with Prime Factorization
| 5 | 169, 660, 247, 403, 155 |
| 13 | 169, 132, 247, 403, 31 |
| 31 | 13, 132, 19, 31, 31 |
| 13, 132, 19, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 31 x 13 x 132 x 19 x 1 x 1 = 65697060
Therefore, the lowest common multiple of 169,660,247,403,155 is 65697060.
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 660 x 247 x 403 x 155 = 1720934486700
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
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
247 : 1, 13, 19, 247
403 : 1, 13, 31, 403
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,660,247,403,155, is 1.
Now, the common factors can be found like this.
169:13x 13
660:2x 2x 3x 5x 11
247:13x 19
403:13x 31
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 13x 31 = 26195
Therefore, the value for common factors is 26195.
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 = 1720934486700/(1x26195)
LCM = 1720934486700/26195
LCM = 65697060
Thus, we can understand that the LCM of 169,660,247,403,155 is 65697060.
