Given numbers are 214,434,456,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 214,434,456,686 is 518805336.
Find LCM of 214,434,456,686 with Prime Factorization
2 | 214, 434, 456, 686 |
7 | 107, 217, 228, 343 |
107, 31, 228, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 107 x 31 x 228 x 49 = 518805336
Therefore, the lowest common multiple of 214,434,456,686 is 518805336.
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.
214 x 434 x 456 x 686 = 29053098816
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.
214 : 1, 2, 107, 214
434 : 1, 2, 7, 14, 31, 62, 217, 434
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,434,456,686, is 2.
Now, the common factors can be found like this.
214:2x 107
434:2x 7x 31
456:2x 2x 2x 3x 19
686:2x 7x 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 7 = 28
Therefore, the value for common factors is 28.
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 = 29053098816/(2x28)
LCM = 29053098816/56
LCM = 518805336
Thus, we can understand that the LCM of 214,434,456,686 is 518805336.
