Given numbers are 2,641,992,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 2,641,992,641 is 635872.
Find LCM of 2,641,992,641 with Prime Factorization
| 2 | 2, 641, 992, 641 |
| 641 | 1, 641, 496, 641 |
| 1, 1, 496, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 641 x 1 x 1 x 496 x 1 = 635872
Therefore, the lowest common multiple of 2,641,992,641 is 635872.
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.
2 x 641 x 992 x 641 = 815187904
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.
2 : 1, 2
641 : 1, 641
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,641,992,641, is 1.
Now, the common factors can be found like this.
2:2
641:641
992:2x 2x 2x 2x 2x 31
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 641 = 1282
Therefore, the value for common factors is 1282.
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 = 815187904/(1x1282)
LCM = 815187904/1282
LCM = 635872
Thus, we can understand that the LCM of 2,641,992,641 is 635872.
