Find LCM of 820,375,417,738,209 with Prime Factorization
| 2 | 820, 375, 417, 738, 209 |
| 3 | 410, 375, 417, 369, 209 |
| 5 | 410, 125, 139, 123, 209 |
| 41 | 82, 25, 139, 123, 209 |
| 2, 25, 139, 3, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 2 x 25 x 139 x 3 x 209 = 5359909500
Therefore, the lowest common multiple of 820,375,417,738,209 is 5359909500.
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.
820 x 375 x 417 x 738 x 209 = 19778066055000
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
375 : 1, 3, 5, 15, 25, 75, 125, 375
417 : 1, 3, 139, 417
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,375,417,738,209, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
375:3x 5x 5x 5
417:3x 139
738:2x 3x 3x 41
209:11x 19
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 5x 41 = 3690
Therefore, the value for common factors is 3690.
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 = 19778066055000/(1x3690)
LCM = 19778066055000/3690
LCM = 5359909500
Thus, we can understand that the LCM of 820,375,417,738,209 is 5359909500.
