Given numbers are 984,861,783,807,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 984,861,783,807,989 is 478279996488.
Find LCM of 984,861,783,807,989 with Prime Factorization
| 3 | 984, 861, 783, 807, 989 |
| 41 | 328, 287, 261, 269, 989 |
| 8, 7, 261, 269, 989 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 8 x 7 x 261 x 269 x 989 = 478279996488
Therefore, the lowest common multiple of 984,861,783,807,989 is 478279996488.
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.
984 x 861 x 783 x 807 x 989 = 529455956112216
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
861 : 1, 3, 7, 21, 41, 123, 287, 861
783 : 1, 3, 9, 27, 29, 87, 261, 783
807 : 1, 3, 269, 807
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,861,783,807,989, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
861:3x 7x 41
783:3x 3x 3x 29
807:3x 269
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 41 = 1107
Therefore, the value for common factors is 1107.
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 = 529455956112216/(1x1107)
LCM = 529455956112216/1107
LCM = 478279996488
Thus, we can understand that the LCM of 984,861,783,807,989 is 478279996488.
