The LCM of 289,224,485,210,971 is 91459344480.
Find LCM of 289,224,485,210,971 with Prime Factorization
| 2 | 289, 224, 485, 210, 971 |
| 5 | 289, 112, 485, 105, 971 |
| 7 | 289, 112, 97, 21, 971 |
| 289, 16, 97, 3, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 289 x 16 x 97 x 3 x 971 = 91459344480
Therefore, the lowest common multiple of 289,224,485,210,971 is 91459344480.
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.
289 x 224 x 485 x 210 x 971 = 6402154113600
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.
289 : 1, 17, 289
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
485 : 1, 5, 97, 485
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,224,485,210,971, is 1.
Now, the common factors can be found like this.
289:17x 17
224:2x 2x 2x 2x 2x 7
485:5x 97
210:2x 3x 5x 7
971:971
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 7 = 70
Therefore, the value for common factors is 70.
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 = 6402154113600/(1x70)
LCM = 6402154113600/70
LCM = 91459344480
Thus, we can understand that the LCM of 289,224,485,210,971 is 91459344480.
