Given numbers are 221,141,122,306
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,141,122,306 is 11404926.
Find LCM of 221,141,122,306 with Prime Factorization
2 | 221, 141, 122, 306 |
3 | 221, 141, 61, 153 |
17 | 221, 47, 61, 51 |
13, 47, 61, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 13 x 47 x 61 x 3 = 11404926
Therefore, the lowest common multiple of 221,141,122,306 is 11404926.
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.
221 x 141 x 122 x 306 = 1163302452
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.
221 : 1, 13, 17, 221
141 : 1, 3, 47, 141
122 : 1, 2, 61, 122
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,141,122,306, is 1.
Now, the common factors can be found like this.
221:13x 17
141:3x 47
122:2x 61
306:2x 3x 3x 17
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 17 = 102
Therefore, the value for common factors is 102.
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 = 1163302452/(1x102)
LCM = 1163302452/102
LCM = 11404926
Thus, we can understand that the LCM of 221,141,122,306 is 11404926.
