Given numbers are 816,712,905,839,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,712,905,839,988 is 13620330899760.
Find LCM of 816,712,905,839,988 with Prime Factorization
| 2 | 816, 712, 905, 839, 988 |
| 2 | 408, 356, 905, 839, 494 |
| 2 | 204, 178, 905, 839, 247 |
| 102, 89, 905, 839, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 102 x 89 x 905 x 839 x 247 = 13620330899760
Therefore, the lowest common multiple of 816,712,905,839,988 is 13620330899760.
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.
816 x 712 x 905 x 839 x 988 = 435850588792320
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
712 : 1, 2, 4, 8, 89, 178, 356, 712
905 : 1, 5, 181, 905
839 : 1, 839
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,712,905,839,988, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
712:2x 2x 2x 89
905:5x 181
839:839
988:2x 2x 13x 19
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 2x 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 435850588792320/(1x32)
LCM = 435850588792320/32
LCM = 13620330899760
Thus, we can understand that the LCM of 816,712,905,839,988 is 13620330899760.
