Given numbers are 979,623,852,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,623,852,781 is 5838756.
Find LCM of 979,623,852,781 with Prime Factorization
| 11 | 979, 623, 852, 781 |
| 71 | 89, 623, 852, 71 |
| 89 | 89, 623, 12, 1 |
| 1, 7, 12, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 89 x 1 x 7 x 12 x 1 = 5838756
Therefore, the lowest common multiple of 979,623,852,781 is 5838756.
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 623 x 852 x 781 = 405846090804
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
623 : 1, 7, 89, 623
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,623,852,781, is 1.
Now, the common factors can be found like this.
979:11x 89
623:7x 89
852:2x 2x 3x 71
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 71x 89 = 69509
Therefore, the value for common factors is 69509.
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 = 405846090804/(1x69509)
LCM = 405846090804/69509
LCM = 5838756
Thus, we can understand that the LCM of 979,623,852,781 is 5838756.
