Given numbers are 755,487,985,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,487,985,989 is 71637171605.
Find LCM of 755,487,985,989 with Prime Factorization
| 5 | 755, 487, 985, 989 |
| 151, 487, 197, 989 |
Multiply the prime numbers at the bottom and the left side.
5 x 151 x 487 x 197 x 989 = 71637171605
Therefore, the lowest common multiple of 755,487,985,989 is 71637171605.
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.
755 x 487 x 985 x 989 = 358185858025
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.
755 : 1, 5, 151, 755
487 : 1, 487
985 : 1, 5, 197, 985
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,487,985,989, is 1.
Now, the common factors can be found like this.
755:5x 151
487:487
985:5x 197
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.
5 = 5
Therefore, the value for common factors is 5.
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 = 358185858025/(1x5)
LCM = 358185858025/5
LCM = 71637171605
Thus, we can understand that the LCM of 755,487,985,989 is 71637171605.
