Given numbers are 251,410,215,298,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,410,215,298,745 is 659344370.
Find LCM of 251,410,215,298,745 with Prime Factorization
| 2 | 251, 410, 215, 298, 745 |
| 5 | 251, 205, 215, 149, 745 |
| 149 | 251, 41, 43, 149, 149 |
| 251, 41, 43, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 149 x 251 x 41 x 43 x 1 x 1 = 659344370
Therefore, the lowest common multiple of 251,410,215,298,745 is 659344370.
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.
251 x 410 x 215 x 298 x 745 = 4912115556500
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.
251 : 1, 251
410 : 1, 2, 5, 10, 41, 82, 205, 410
215 : 1, 5, 43, 215
298 : 1, 2, 149, 298
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,410,215,298,745, is 1.
Now, the common factors can be found like this.
251:251
410:2x 5x 41
215:5x 43
298:2x 149
745:5x 149
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 5x 149 = 7450
Therefore, the value for common factors is 7450.
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 = 4912115556500/(1x7450)
LCM = 4912115556500/7450
LCM = 659344370
Thus, we can understand that the LCM of 251,410,215,298,745 is 659344370.
