Given numbers are 197,788,212,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,788,212,840 is 8770440.
Find LCM of 197,788,212,840 with Prime Factorization
| 2 | 197, 788, 212, 840 |
| 2 | 197, 394, 106, 420 |
| 197 | 197, 197, 53, 210 |
| 1, 1, 53, 210 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 197 x 1 x 1 x 53 x 210 = 8770440
Therefore, the lowest common multiple of 197,788,212,840 is 8770440.
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.
197 x 788 x 212 x 840 = 27644426880
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.
197 : 1, 197
788 : 1, 2, 4, 197, 394, 788
212 : 1, 2, 4, 53, 106, 212
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,788,212,840, is 1.
Now, the common factors can be found like this.
197:197
788:2x 2x 197
212:2x 2x 53
840:2x 2x 2x 3x 5x 7
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 2x 2x 197 = 3152
Therefore, the value for common factors is 3152.
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 = 27644426880/(1x3152)
LCM = 27644426880/3152
LCM = 8770440
Thus, we can understand that the LCM of 197,788,212,840 is 8770440.
