Given numbers are 127,865,460,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,865,460,690 is 30319980.
Find LCM of 127,865,460,690 with Prime Factorization
| 2 | 127, 865, 460, 690 |
| 5 | 127, 865, 230, 345 |
| 23 | 127, 173, 46, 69 |
| 127, 173, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 127 x 173 x 2 x 3 = 30319980
Therefore, the lowest common multiple of 127,865,460,690 is 30319980.
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.
127 x 865 x 460 x 690 = 34867977000
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.
127 : 1, 127
865 : 1, 5, 173, 865
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,865,460,690, is 1.
Now, the common factors can be found like this.
127:127
865:5x 173
460:2x 2x 5x 23
690:2x 3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 23 = 1150
Therefore, the value for common factors is 1150.
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 = 34867977000/(1x1150)
LCM = 34867977000/1150
LCM = 30319980
Thus, we can understand that the LCM of 127,865,460,690 is 30319980.
