Given numbers are 969,210,646,270
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,210,646,270 is 610470.
Find LCM of 969,210,646,270 with Prime Factorization
| 2 | 969, 210, 646, 270 |
| 3 | 969, 105, 323, 135 |
| 5 | 323, 35, 323, 45 |
| 17 | 323, 7, 323, 9 |
| 19 | 19, 7, 19, 9 |
| 1, 7, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 19 x 1 x 7 x 1 x 9 = 610470
Therefore, the lowest common multiple of 969,210,646,270 is 610470.
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.
969 x 210 x 646 x 270 = 35492725800
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
646 : 1, 2, 17, 19, 34, 38, 323, 646
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,210,646,270, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
210:2x 3x 5x 7
646:2x 17x 19
270:2x 3x 3x 3x 5
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 3x 5x 17x 19 = 58140
Therefore, the value for common factors is 58140.
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 = 35492725800/(1x58140)
LCM = 35492725800/58140
LCM = 610470
Thus, we can understand that the LCM of 969,210,646,270 is 610470.
