Given numbers are 513,435,969,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,435,969,978 is 412241670.
Find LCM of 513,435,969,978 with Prime Factorization
| 3 | 513, 435, 969, 978 |
| 19 | 171, 145, 323, 326 |
| 9, 145, 17, 326 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 9 x 145 x 17 x 326 = 412241670
Therefore, the lowest common multiple of 513,435,969,978 is 412241670.
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.
513 x 435 x 969 x 978 = 211479976710
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
435 : 1, 3, 5, 15, 29, 87, 145, 435
969 : 1, 3, 17, 19, 51, 57, 323, 969
978 : 1, 2, 3, 6, 163, 326, 489, 978
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,435,969,978, is 3.
Now, the common factors can be found like this.
513:3x 3x 3x 19
435:3x 5x 29
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.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 211479976710/(3x171)
LCM = 211479976710/513
LCM = 412241670
Thus, we can understand that the LCM of 513,435,969,978 is 412241670.
