Given numbers are 161,637,460,417,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,637,460,417,661 is 80767153740.
Find LCM of 161,637,460,417,661 with Prime Factorization
| 7 | 161, 637, 460, 417, 661 |
| 23 | 23, 91, 460, 417, 661 |
| 1, 91, 20, 417, 661 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 1 x 91 x 20 x 417 x 661 = 80767153740
Therefore, the lowest common multiple of 161,637,460,417,661 is 80767153740.
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 637 x 460 x 417 x 661 = 13003511752140
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
637 : 1, 7, 13, 49, 91, 637
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
417 : 1, 3, 139, 417
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,637,460,417,661, is 1.
Now, the common factors can be found like this.
161:7x 23
637:7x 7x 13
460:2x 2x 5x 23
417:3x 139
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 13003511752140/(1x161)
LCM = 13003511752140/161
LCM = 80767153740
Thus, we can understand that the LCM of 161,637,460,417,661 is 80767153740.
