Given numbers are 455,133,989,122,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,133,989,122,210 is 3129265230.
Find LCM of 455,133,989,122,210 with Prime Factorization
| 2 | 455, 133, 989, 122, 210 |
| 5 | 455, 133, 989, 61, 105 |
| 7 | 91, 133, 989, 61, 21 |
| 13, 19, 989, 61, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 19 x 989 x 61 x 3 = 3129265230
Therefore, the lowest common multiple of 455,133,989,122,210 is 3129265230.
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.
455 x 133 x 989 x 122 x 210 = 1533339962700
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
133 : 1, 7, 19, 133
989 : 1, 23, 43, 989
122 : 1, 2, 61, 122
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 455,133,989,122,210, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
133:7x 19
989:23x 43
122:2x 61
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 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 1533339962700/(1x490)
LCM = 1533339962700/490
LCM = 3129265230
Thus, we can understand that the LCM of 455,133,989,122,210 is 3129265230.
