Given numbers are 649,979,397,993,801
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,979,397,993,801 is 68311797543.
Find LCM of 649,979,397,993,801 with Prime Factorization
| 3 | 649, 979, 397, 993, 801 |
| 11 | 649, 979, 397, 331, 267 |
| 89 | 59, 89, 397, 331, 267 |
| 59, 1, 397, 331, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 89 x 59 x 1 x 397 x 331 x 3 = 68311797543
Therefore, the lowest common multiple of 649,979,397,993,801 is 68311797543.
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 397 x 993 x 801 = 200631749383791
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
397 : 1, 397
993 : 1, 3, 331, 993
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,979,397,993,801, is 1.
Now, the common factors can be found like this.
649:11x 59
979:11x 89
397:397
993:3x 331
801:3x 3x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 89 = 2937
Therefore, the value for common factors is 2937.
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 = 200631749383791/(1x2937)
LCM = 200631749383791/2937
LCM = 68311797543
Thus, we can understand that the LCM of 649,979,397,993,801 is 68311797543.
