Given numbers are 534,791,815,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 534,791,815,189 is 3098259990.
Find LCM of 534,791,815,189 with Prime Factorization
| 3 | 534, 791, 815, 189 |
| 7 | 178, 791, 815, 63 |
| 178, 113, 815, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 178 x 113 x 815 x 9 = 3098259990
Therefore, the lowest common multiple of 534,791,815,189 is 3098259990.
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.
534 x 791 x 815 x 189 = 65063459790
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.
534 : 1, 2, 3, 6, 89, 178, 267, 534
791 : 1, 7, 113, 791
815 : 1, 5, 163, 815
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 534,791,815,189, is 1.
Now, the common factors can be found like this.
534:2x 3x 89
791:7x 113
815:5x 163
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 65063459790/(1x21)
LCM = 65063459790/21
LCM = 3098259990
Thus, we can understand that the LCM of 534,791,815,189 is 3098259990.
