Given numbers are 762,540,486,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,540,486,991 is 611665020.
Find LCM of 762,540,486,991 with Prime Factorization
| 2 | 762, 540, 486, 991 |
| 3 | 381, 270, 243, 991 |
| 3 | 127, 90, 81, 991 |
| 3 | 127, 30, 27, 991 |
| 127, 10, 9, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 127 x 10 x 9 x 991 = 611665020
Therefore, the lowest common multiple of 762,540,486,991 is 611665020.
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.
762 x 540 x 486 x 991 = 198179466480
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,540,486,991, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
540:2x 2x 3x 3x 3x 5
486:2x 3x 3x 3x 3x 3
991:991
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 198179466480/(1x324)
LCM = 198179466480/324
LCM = 611665020
Thus, we can understand that the LCM of 762,540,486,991 is 611665020.
