Given numbers are 131,697,285,686,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,697,285,686,212 is 1892251746420.
Find LCM of 131,697,285,686,212 with Prime Factorization
2 | 131, 697, 285, 686, 212 |
131, 697, 285, 343, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 697 x 285 x 343 x 106 = 1892251746420
Therefore, the lowest common multiple of 131,697,285,686,212 is 1892251746420.
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.
131 x 697 x 285 x 686 x 212 = 3784503492840
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.
131 : 1, 131
697 : 1, 17, 41, 697
285 : 1, 3, 5, 15, 19, 57, 95, 285
686 : 1, 2, 7, 14, 49, 98, 343, 686
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,697,285,686,212, is 1.
Now, the common factors can be found like this.
131:131
697:17x 41
285:3x 5x 19
686:2x 7x 7x 7
212:2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 3784503492840/(1x2)
LCM = 3784503492840/2
LCM = 1892251746420
Thus, we can understand that the LCM of 131,697,285,686,212 is 1892251746420.
