Given numbers are 212,210,845,621,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 212,210,845,621,669 is 173654912340.
Find LCM of 212,210,845,621,669 with Prime Factorization
| 2 | 212, 210, 845, 621, 669 |
| 3 | 106, 105, 845, 621, 669 |
| 5 | 106, 35, 845, 207, 223 |
| 106, 7, 169, 207, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 106 x 7 x 169 x 207 x 223 = 173654912340
Therefore, the lowest common multiple of 212,210,845,621,669 is 173654912340.
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.
212 x 210 x 845 x 621 x 669 = 15628942110600
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.
212 : 1, 2, 4, 53, 106, 212
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
845 : 1, 5, 13, 65, 169, 845
621 : 1, 3, 9, 23, 27, 69, 207, 621
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,210,845,621,669, is 1.
Now, the common factors can be found like this.
212:2x 2x 53
210:2x 3x 5x 7
845:5x 13x 13
621:3x 3x 3x 23
669:3x 223
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 15628942110600/(1x90)
LCM = 15628942110600/90
LCM = 173654912340
Thus, we can understand that the LCM of 212,210,845,621,669 is 173654912340.
