Given numbers are 813,495,499,978,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,495,499,978,748 is 741944726820.
Find LCM of 813,495,499,978,748 with Prime Factorization
| 2 | 813, 495, 499, 978, 748 |
| 3 | 813, 495, 499, 489, 374 |
| 11 | 271, 165, 499, 163, 374 |
| 271, 15, 499, 163, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 271 x 15 x 499 x 163 x 34 = 741944726820
Therefore, the lowest common multiple of 813,495,499,978,748 is 741944726820.
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.
813 x 495 x 499 x 978 x 748 = 146905055910360
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.
813 : 1, 3, 271, 813
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
499 : 1, 499
978 : 1, 2, 3, 6, 163, 326, 489, 978
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,495,499,978,748, is 1.
Now, the common factors can be found like this.
813:3x 271
495:3x 3x 5x 11
499:499
978:2x 3x 163
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 146905055910360/(1x198)
LCM = 146905055910360/198
LCM = 741944726820
Thus, we can understand that the LCM of 813,495,499,978,748 is 741944726820.
