Given numbers are 220,240,985,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,240,985,899 is 467551920.
Find LCM of 220,240,985,899 with Prime Factorization
| 2 | 220, 240, 985, 899 |
| 2 | 110, 120, 985, 899 |
| 5 | 55, 60, 985, 899 |
| 11, 12, 197, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 12 x 197 x 899 = 467551920
Therefore, the lowest common multiple of 220,240,985,899 is 467551920.
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.
220 x 240 x 985 x 899 = 46755192000
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
985 : 1, 5, 197, 985
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,240,985,899, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
240:2x 2x 2x 2x 3x 5
985:5x 197
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 46755192000/(1x100)
LCM = 46755192000/100
LCM = 467551920
Thus, we can understand that the LCM of 220,240,985,899 is 467551920.
