Given numbers are 127,722,998,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,722,998,788 is 18027590564.
Find LCM of 127,722,998,788 with Prime Factorization
| 2 | 127, 722, 998, 788 |
| 127, 361, 499, 394 |
Multiply the prime numbers at the bottom and the left side.
2 x 127 x 361 x 499 x 394 = 18027590564
Therefore, the lowest common multiple of 127,722,998,788 is 18027590564.
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 722 x 998 x 788 = 72110362256
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
722 : 1, 2, 19, 38, 361, 722
998 : 1, 2, 499, 998
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,722,998,788, is 1.
Now, the common factors can be found like this.
127:127
722:2x 19x 19
998:2x 499
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 72110362256/(1x4)
LCM = 72110362256/4
LCM = 18027590564
Thus, we can understand that the LCM of 127,722,998,788 is 18027590564.
