Given numbers are 681,884,635,861,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,884,635,861,400 is 2194244379600.
Find LCM of 681,884,635,861,400 with Prime Factorization
| 2 | 681, 884, 635, 861, 400 |
| 2 | 681, 442, 635, 861, 200 |
| 3 | 681, 221, 635, 861, 100 |
| 5 | 227, 221, 635, 287, 100 |
| 227, 221, 127, 287, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 227 x 221 x 127 x 287 x 20 = 2194244379600
Therefore, the lowest common multiple of 681,884,635,861,400 is 2194244379600.
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.
681 x 884 x 635 x 861 x 400 = 131654662776000
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.
681 : 1, 3, 227, 681
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
635 : 1, 5, 127, 635
861 : 1, 3, 7, 21, 41, 123, 287, 861
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,884,635,861,400, is 1.
Now, the common factors can be found like this.
681:3x 227
884:2x 2x 13x 17
635:5x 127
861:3x 7x 41
400:2x 2x 2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 131654662776000/(1x60)
LCM = 131654662776000/60
LCM = 2194244379600
Thus, we can understand that the LCM of 681,884,635,861,400 is 2194244379600.
