Given numbers are 161,126,471,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,126,471,298 is 67792914.
Find LCM of 161,126,471,298 with Prime Factorization
| 2 | 161, 126, 471, 298 |
| 3 | 161, 63, 471, 149 |
| 7 | 161, 21, 157, 149 |
| 23, 3, 157, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 3 x 157 x 149 = 67792914
Therefore, the lowest common multiple of 161,126,471,298 is 67792914.
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 126 x 471 x 298 = 2847302388
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
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
471 : 1, 3, 157, 471
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,126,471,298, is 1.
Now, the common factors can be found like this.
161:7x 23
126:2x 3x 3x 7
471:3x 157
298:2x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 2847302388/(1x42)
LCM = 2847302388/42
LCM = 67792914
Thus, we can understand that the LCM of 161,126,471,298 is 67792914.
