Given numbers are 161,154,618,843,444
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,154,618,843,444 is 22758575532.
Find LCM of 161,154,618,843,444 with Prime Factorization
| 2 | 161, 154, 618, 843, 444 |
| 3 | 161, 77, 309, 843, 222 |
| 7 | 161, 77, 103, 281, 74 |
| 23, 11, 103, 281, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 11 x 103 x 281 x 74 = 22758575532
Therefore, the lowest common multiple of 161,154,618,843,444 is 22758575532.
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 154 x 618 x 843 x 444 = 5735161034064
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
154 : 1, 2, 7, 11, 14, 22, 77, 154
618 : 1, 2, 3, 6, 103, 206, 309, 618
843 : 1, 3, 281, 843
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,154,618,843,444, is 1.
Now, the common factors can be found like this.
161:7x 23
154:2x 7x 11
618:2x 3x 103
843:3x 281
444:2x 2x 3x 37
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 5735161034064/(1x252)
LCM = 5735161034064/252
LCM = 22758575532
Thus, we can understand that the LCM of 161,154,618,843,444 is 22758575532.
