Given numbers are 282,628,899,120,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,628,899,120,978 is 129755582760.
Find LCM of 282,628,899,120,978 with Prime Factorization
| 2 | 282, 628, 899, 120, 978 |
| 2 | 141, 314, 899, 60, 489 |
| 3 | 141, 157, 899, 30, 489 |
| 47, 157, 899, 10, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 47 x 157 x 899 x 10 x 163 = 129755582760
Therefore, the lowest common multiple of 282,628,899,120,978 is 129755582760.
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.
282 x 628 x 899 x 120 x 978 = 18684803917440
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
628 : 1, 2, 4, 157, 314, 628
899 : 1, 29, 31, 899
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,628,899,120,978, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
628:2x 2x 157
899:29x 31
120:2x 2x 2x 3x 5
978:2x 3x 163
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 18684803917440/(1x144)
LCM = 18684803917440/144
LCM = 129755582760
Thus, we can understand that the LCM of 282,628,899,120,978 is 129755582760.
