Given numbers are 557,212,969,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,212,969,978 is 18651013548.
Find LCM of 557,212,969,978 with Prime Factorization
| 2 | 557, 212, 969, 978 |
| 3 | 557, 106, 969, 489 |
| 557, 106, 323, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 557 x 106 x 323 x 163 = 18651013548
Therefore, the lowest common multiple of 557,212,969,978 is 18651013548.
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.
557 x 212 x 969 x 978 = 111906081288
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.
557 : 1, 557
212 : 1, 2, 4, 53, 106, 212
969 : 1, 3, 17, 19, 51, 57, 323, 969
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,212,969,978, is 1.
Now, the common factors can be found like this.
557:557
212:2x 2x 53
969:3x 17x 19
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 111906081288/(1x6)
LCM = 111906081288/6
LCM = 18651013548
Thus, we can understand that the LCM of 557,212,969,978 is 18651013548.
