Given numbers are 84,45,70,22,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 84,45,70,22,899 is 12460140.
Find LCM of 84,45,70,22,899 with Prime Factorization
| 2 | 84, 45, 70, 22, 899 |
| 3 | 42, 45, 35, 11, 899 |
| 5 | 14, 15, 35, 11, 899 |
| 7 | 14, 3, 7, 11, 899 |
| 2, 3, 1, 11, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 2 x 3 x 1 x 11 x 899 = 12460140
Therefore, the lowest common multiple of 84,45,70,22,899 is 12460140.
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.
84 x 45 x 70 x 22 x 899 = 5233258800
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.
84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
45 : 1, 3, 5, 9, 15, 45
70 : 1, 2, 5, 7, 10, 14, 35, 70
22 : 1, 2, 11, 22
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 84,45,70,22,899, is 1.
Now, the common factors can be found like this.
84:2x 2x 3x 7
45:3x 3x 5
70:2x 5x 7
22:2x 11
899:29x 31
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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 5233258800/(1x420)
LCM = 5233258800/420
LCM = 12460140
Thus, we can understand that the LCM of 84,45,70,22,899 is 12460140.
