Given numbers are 649,979,164,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,979,164,691 is 6545707564.
Find LCM of 649,979,164,691 with Prime Factorization
| 11 | 649, 979, 164, 691 |
| 59, 89, 164, 691 |
Multiply the prime numbers at the bottom and the left side.
11 x 59 x 89 x 164 x 691 = 6545707564
Therefore, the lowest common multiple of 649,979,164,691 is 6545707564.
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.
649 x 979 x 164 x 691 = 72002783204
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.
649 : 1, 11, 59, 649
979 : 1, 11, 89, 979
164 : 1, 2, 4, 41, 82, 164
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,979,164,691, is 1.
Now, the common factors can be found like this.
649:11x 59
979:11x 89
164:2x 2x 41
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 72002783204/(1x11)
LCM = 72002783204/11
LCM = 6545707564
Thus, we can understand that the LCM of 649,979,164,691 is 6545707564.
