Given numbers are 741,240,122,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,240,122,988 is 3616080.
Find LCM of 741,240,122,988 with Prime Factorization
| 2 | 741, 240, 122, 988 |
| 2 | 741, 120, 61, 494 |
| 3 | 741, 60, 61, 247 |
| 13 | 247, 20, 61, 247 |
| 19 | 19, 20, 61, 19 |
| 1, 20, 61, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 19 x 1 x 20 x 61 x 1 = 3616080
Therefore, the lowest common multiple of 741,240,122,988 is 3616080.
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.
741 x 240 x 122 x 988 = 21436122240
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
122 : 1, 2, 61, 122
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,240,122,988, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
240:2x 2x 2x 2x 3x 5
122:2x 61
988:2x 2x 13x 19
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 3x 13x 19 = 5928
Therefore, the value for common factors is 5928.
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 = 21436122240/(1x5928)
LCM = 21436122240/5928
LCM = 3616080
Thus, we can understand that the LCM of 741,240,122,988 is 3616080.
