Given numbers are 161,884,270,942,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,884,270,942,747 is 250374245940.
Find LCM of 161,884,270,942,747 with Prime Factorization
| 2 | 161, 884, 270, 942, 747 |
| 3 | 161, 442, 135, 471, 747 |
| 3 | 161, 442, 45, 157, 249 |
| 161, 442, 15, 157, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 161 x 442 x 15 x 157 x 83 = 250374245940
Therefore, the lowest common multiple of 161,884,270,942,747 is 250374245940.
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 884 x 270 x 942 x 747 = 27040418561520
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
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
942 : 1, 2, 3, 6, 157, 314, 471, 942
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,884,270,942,747, is 1.
Now, the common factors can be found like this.
161:7x 23
884:2x 2x 13x 17
270:2x 3x 3x 3x 5
942:2x 3x 157
747:3x 3x 83
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 3 = 108
Therefore, the value for common factors is 108.
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 = 27040418561520/(1x108)
LCM = 27040418561520/108
LCM = 250374245940
Thus, we can understand that the LCM of 161,884,270,942,747 is 250374245940.
