Given numbers are 120,958,284,142,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,958,284,142,986 is 2011972440.
Find LCM of 120,958,284,142,986 with Prime Factorization
| 2 | 120, 958, 284, 142, 986 |
| 2 | 60, 479, 142, 71, 493 |
| 71 | 30, 479, 71, 71, 493 |
| 30, 479, 1, 1, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 30 x 479 x 1 x 1 x 493 = 2011972440
Therefore, the lowest common multiple of 120,958,284,142,986 is 2011972440.
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.
120 x 958 x 284 x 142 x 986 = 4571201383680
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
958 : 1, 2, 479, 958
284 : 1, 2, 4, 71, 142, 284
142 : 1, 2, 71, 142
986 : 1, 2, 17, 29, 34, 58, 493, 986
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,958,284,142,986, is 2.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
958:2x 479
284:2x 2x 71
142:2x 71
986:2x 17x 29
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 2x 71 = 1136
Therefore, the value for common factors is 1136.
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 = 4571201383680/(2x1136)
LCM = 4571201383680/2272
LCM = 2011972440
Thus, we can understand that the LCM of 120,958,284,142,986 is 2011972440.
