Given numbers are 411,802,639,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 411,802,639,197 is 13831268742.
Find LCM of 411,802,639,197 with Prime Factorization
| 3 | 411, 802, 639, 197 |
| 137, 802, 213, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 137 x 802 x 213 x 197 = 13831268742
Therefore, the lowest common multiple of 411,802,639,197 is 13831268742.
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.
411 x 802 x 639 x 197 = 41493806226
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.
411 : 1, 3, 137, 411
802 : 1, 2, 401, 802
639 : 1, 3, 9, 71, 213, 639
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,802,639,197, is 1.
Now, the common factors can be found like this.
411:3x 137
802:2x 401
639:3x 3x 71
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 41493806226/(1x3)
LCM = 41493806226/3
LCM = 13831268742
Thus, we can understand that the LCM of 411,802,639,197 is 13831268742.
