Given numbers are 555,786,885,987,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 555,786,885,987,978 is 460076222130.
Find LCM of 555,786,885,987,978 with Prime Factorization
| 2 | 555, 786, 885, 987, 978 |
| 3 | 555, 393, 885, 987, 489 |
| 5 | 185, 131, 295, 329, 163 |
| 37, 131, 59, 329, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 131 x 59 x 329 x 163 = 460076222130
Therefore, the lowest common multiple of 555,786,885,987,978 is 460076222130.
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.
555 x 786 x 885 x 987 x 978 = 372661739925300
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
786 : 1, 2, 3, 6, 131, 262, 393, 786
885 : 1, 3, 5, 15, 59, 177, 295, 885
987 : 1, 3, 7, 21, 47, 141, 329, 987
978 : 1, 2, 3, 6, 163, 326, 489, 978
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,786,885,987,978, is 3.
Now, the common factors can be found like this.
555:3x 5x 37
786:2x 3x 131
885:3x 5x 59
987:3x 7x 47
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 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 372661739925300/(3x270)
LCM = 372661739925300/810
LCM = 460076222130
Thus, we can understand that the LCM of 555,786,885,987,978 is 460076222130.
