Given numbers are 487,392,113,196
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,392,113,196 is 21572152.
Find LCM of 487,392,113,196 with Prime Factorization
2 | 487, 392, 113, 196 |
2 | 487, 196, 113, 98 |
7 | 487, 49, 113, 98 |
7 | 487, 7, 113, 14 |
487, 1, 113, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 487 x 1 x 113 x 2 = 21572152
Therefore, the lowest common multiple of 487,392,113,196 is 21572152.
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.
487 x 392 x 113 x 196 = 4228141792
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.
487 : 1, 487
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
113 : 1, 113
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,392,113,196, is 1.
Now, the common factors can be found like this.
487:487
392:2x 2x 2x 7x 7
113:113
196:2x 2x 7x 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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 4228141792/(1x196)
LCM = 4228141792/196
LCM = 21572152
Thus, we can understand that the LCM of 487,392,113,196 is 21572152.
