Given numbers are 161,185,589,713,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,185,589,713,445 is 1561359485.
Find LCM of 161,185,589,713,445 with Prime Factorization
| 5 | 161, 185, 589, 713, 445 |
| 23 | 161, 37, 589, 713, 89 |
| 31 | 7, 37, 589, 31, 89 |
| 7, 37, 19, 1, 89 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 31 x 7 x 37 x 19 x 1 x 89 = 1561359485
Therefore, the lowest common multiple of 161,185,589,713,445 is 1561359485.
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.
161 x 185 x 589 x 713 x 445 = 5566246564025
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.
161 : 1, 7, 23, 161
185 : 1, 5, 37, 185
589 : 1, 19, 31, 589
713 : 1, 23, 31, 713
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,185,589,713,445, is 1.
Now, the common factors can be found like this.
161:7x 23
185:5x 37
589:19x 31
713:23x 31
445:5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23x 31 = 3565
Therefore, the value for common factors is 3565.
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 = 5566246564025/(1x3565)
LCM = 5566246564025/3565
LCM = 1561359485
Thus, we can understand that the LCM of 161,185,589,713,445 is 1561359485.
