Given numbers are 754,120,986,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,120,986,580 is 769080.
Find LCM of 754,120,986,580 with Prime Factorization
| 2 | 754, 120, 986, 580 |
| 2 | 377, 60, 493, 290 |
| 5 | 377, 30, 493, 145 |
| 29 | 377, 6, 493, 29 |
| 13, 6, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 13 x 6 x 17 x 1 = 769080
Therefore, the lowest common multiple of 754,120,986,580 is 769080.
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.
754 x 120 x 986 x 580 = 51743702400
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
986 : 1, 2, 17, 29, 34, 58, 493, 986
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,120,986,580, is 2.
Now, the common factors can be found like this.
754:2x 13x 29
120:2x 2x 2x 3x 5
986:2x 17x 29
580:2x 2x 5x 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 5x 29x 29 = 33640
Therefore, the value for common factors is 33640.
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 = 51743702400/(2x33640)
LCM = 51743702400/67280
LCM = 769080
Thus, we can understand that the LCM of 754,120,986,580 is 769080.
