Given numbers are 546,991,707,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,991,707,393 is 7159108866.
Find LCM of 546,991,707,393 with Prime Factorization
| 3 | 546, 991, 707, 393 |
| 7 | 182, 991, 707, 131 |
| 26, 991, 101, 131 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 26 x 991 x 101 x 131 = 7159108866
Therefore, the lowest common multiple of 546,991,707,393 is 7159108866.
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.
546 x 991 x 707 x 393 = 150341286186
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
991 : 1, 991
707 : 1, 7, 101, 707
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,991,707,393, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
991:991
707:7x 101
393:3x 131
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 = 150341286186/(1x21)
LCM = 150341286186/21
LCM = 7159108866
Thus, we can understand that the LCM of 546,991,707,393 is 7159108866.
