Given numbers are 222,840,868,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 222,840,868,669 is 214856040.
Find LCM of 222,840,868,669 with Prime Factorization
| 2 | 222, 840, 868, 669 |
| 2 | 111, 420, 434, 669 |
| 3 | 111, 210, 217, 669 |
| 7 | 37, 70, 217, 223 |
| 37, 10, 31, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 37 x 10 x 31 x 223 = 214856040
Therefore, the lowest common multiple of 222,840,868,669 is 214856040.
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.
222 x 840 x 868 x 669 = 108287444160
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,840,868,669, is 1.
Now, the common factors can be found like this.
222:2x 3x 37
840:2x 2x 2x 3x 5x 7
868:2x 2x 7x 31
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 2x 2x 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 108287444160/(1x504)
LCM = 108287444160/504
LCM = 214856040
Thus, we can understand that the LCM of 222,840,868,669 is 214856040.
