Given numbers are 979,782,451,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,782,451,231 is 659162658.
Find LCM of 979,782,451,231 with Prime Factorization
| 11 | 979, 782, 451, 231 |
| 89, 782, 41, 21 |
Multiply the prime numbers at the bottom and the left side.
11 x 89 x 782 x 41 x 21 = 659162658
Therefore, the lowest common multiple of 979,782,451,231 is 659162658.
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.
979 x 782 x 451 x 231 = 79758681618
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.
979 : 1, 11, 89, 979
782 : 1, 2, 17, 23, 34, 46, 391, 782
451 : 1, 11, 41, 451
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,782,451,231, is 1.
Now, the common factors can be found like this.
979:11x 89
782:2x 17x 23
451:11x 41
231:3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 79758681618/(1x121)
LCM = 79758681618/121
LCM = 659162658
Thus, we can understand that the LCM of 979,782,451,231 is 659162658.
