Given numbers are 999,988,778,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 999,988,778,557 is 213858851076.
Find LCM of 999,988,778,557 with Prime Factorization
| 2 | 999, 988, 778, 557 |
| 999, 494, 389, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 999 x 494 x 389 x 557 = 213858851076
Therefore, the lowest common multiple of 999,988,778,557 is 213858851076.
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.
999 x 988 x 778 x 557 = 427717702152
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.
999 : 1, 3, 9, 27, 37, 111, 333, 999
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
778 : 1, 2, 389, 778
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,988,778,557, is 1.
Now, the common factors can be found like this.
999:3x 3x 3x 37
988:2x 2x 13x 19
778:2x 389
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 427717702152/(1x2)
LCM = 427717702152/2
LCM = 213858851076
Thus, we can understand that the LCM of 999,988,778,557 is 213858851076.
