The LCM of 665,285,746,210 is 1488270.
Find LCM of 665,285,746,210 with Prime Factorization
| 2 | 665, 285, 746, 210 |
| 3 | 665, 285, 373, 105 |
| 5 | 665, 95, 373, 35 |
| 7 | 133, 19, 373, 7 |
| 19 | 19, 19, 373, 1 |
| 1, 1, 373, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 19 x 1 x 1 x 373 x 1 = 1488270
Therefore, the lowest common multiple of 665,285,746,210 is 1488270.
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.
665 x 285 x 746 x 210 = 29690986500
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
285 : 1, 3, 5, 15, 19, 57, 95, 285
746 : 1, 2, 373, 746
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,285,746,210, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
285:3x 5x 19
746:2x 373
210:2x 3x 5x 7
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 5x 5x 7x 19 = 19950
Therefore, the value for common factors is 19950.
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 = 29690986500/(1x19950)
LCM = 29690986500/19950
LCM = 1488270
Thus, we can understand that the LCM of 665,285,746,210 is 1488270.
