Given numbers are 625,289,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 625,289,210 is 7586250.
Find LCM of 625,289,210 with Prime Factorization
| 5 | 625, 289, 210 |
| 125, 289, 42 |
Multiply the prime numbers at the bottom and the left side.
5 x 125 x 289 x 42 = 7586250
Therefore, the lowest common multiple of 625,289,210 is 7586250.
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.
625 x 289 x 210 = 37931250
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.
625 : 1, 5, 25, 125, 625
289 : 1, 17, 289
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 625,289,210, is 1.
Now, the common factors can be found like this.
625:5x 5x 5x 5
289:17x 17
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.
5 = 5
Therefore, the value for common factors is 5.
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 = 37931250/(1x5)
LCM = 37931250/5
LCM = 7586250
Thus, we can understand that the LCM of 625,289,210 is 7586250.
