Given numbers are 518,925,190,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,925,190,821 is 202007050.
Find LCM of 518,925,190,821 with Prime Factorization
| 2 | 518, 925, 190, 821 |
| 5 | 259, 925, 95, 821 |
| 37 | 259, 185, 19, 821 |
| 7, 5, 19, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 37 x 7 x 5 x 19 x 821 = 202007050
Therefore, the lowest common multiple of 518,925,190,821 is 202007050.
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.
518 x 925 x 190 x 821 = 74742608500
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
925 : 1, 5, 25, 37, 185, 925
190 : 1, 2, 5, 10, 19, 38, 95, 190
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,925,190,821, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
925:5x 5x 37
190:2x 5x 19
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 37 = 370
Therefore, the value for common factors is 370.
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 = 74742608500/(1x370)
LCM = 74742608500/370
LCM = 202007050
Thus, we can understand that the LCM of 518,925,190,821 is 202007050.
