Given numbers are 758,916,986,978,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 758,916,986,978,890 is 37243498754460.
Find LCM of 758,916,986,978,890 with Prime Factorization
| 2 | 758, 916, 986, 978, 890 |
| 379, 458, 493, 489, 445 |
Multiply the prime numbers at the bottom and the left side.
2 x 379 x 458 x 493 x 489 x 445 = 37243498754460
Therefore, the lowest common multiple of 758,916,986,978,890 is 37243498754460.
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.
758 x 916 x 986 x 978 x 890 = 595895980071360
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.
758 : 1, 2, 379, 758
916 : 1, 2, 4, 229, 458, 916
986 : 1, 2, 17, 29, 34, 58, 493, 986
978 : 1, 2, 3, 6, 163, 326, 489, 978
890 : 1, 2, 5, 10, 89, 178, 445, 890
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,916,986,978,890, is 2.
Now, the common factors can be found like this.
758:2x 379
916:2x 2x 229
986:2x 17x 29
978:2x 3x 163
890:2x 5x 89
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 2 = 8
Therefore, the value for common factors is 8.
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 = 595895980071360/(2x8)
LCM = 595895980071360/16
LCM = 37243498754460
Thus, we can understand that the LCM of 758,916,986,978,890 is 37243498754460.
