Given numbers are 220,247,741,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,247,741,129 is 7009860.
Find LCM of 220,247,741,129 with Prime Factorization
| 3 | 220, 247, 741, 129 |
| 13 | 220, 247, 247, 43 |
| 19 | 220, 19, 19, 43 |
| 220, 1, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 19 x 220 x 1 x 1 x 43 = 7009860
Therefore, the lowest common multiple of 220,247,741,129 is 7009860.
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.
220 x 247 x 741 x 129 = 5194306260
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
247 : 1, 13, 19, 247
741 : 1, 3, 13, 19, 39, 57, 247, 741
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,247,741,129, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
247:13x 19
741:3x 13x 19
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 19 = 741
Therefore, the value for common factors is 741.
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 = 5194306260/(1x741)
LCM = 5194306260/741
LCM = 7009860
Thus, we can understand that the LCM of 220,247,741,129 is 7009860.
