Given numbers are 161,499,998,216,148
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,499,998,216,148 is 642069288.
Find LCM of 161,499,998,216,148 with Prime Factorization
| 2 | 161, 499, 998, 216, 148 |
| 2 | 161, 499, 499, 108, 74 |
| 499 | 161, 499, 499, 54, 37 |
| 161, 1, 1, 54, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 499 x 161 x 1 x 1 x 54 x 37 = 642069288
Therefore, the lowest common multiple of 161,499,998,216,148 is 642069288.
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 499 x 998 x 216 x 148 = 2563140597696
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
499 : 1, 499
998 : 1, 2, 499, 998
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
148 : 1, 2, 4, 37, 74, 148
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,499,998,216,148, is 1.
Now, the common factors can be found like this.
161:7x 23
499:499
998:2x 499
216:2x 2x 2x 3x 3x 3
148:2x 2x 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 2x 499 = 3992
Therefore, the value for common factors is 3992.
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 = 2563140597696/(1x3992)
LCM = 2563140597696/3992
LCM = 642069288
Thus, we can understand that the LCM of 161,499,998,216,148 is 642069288.
