Given numbers are 646,567,969,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,567,969,930 is 56773710.
Find LCM of 646,567,969,930 with Prime Factorization
| 2 | 646, 567, 969, 930 |
| 3 | 323, 567, 969, 465 |
| 17 | 323, 189, 323, 155 |
| 19 | 19, 189, 19, 155 |
| 1, 189, 1, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 1 x 189 x 1 x 155 = 56773710
Therefore, the lowest common multiple of 646,567,969,930 is 56773710.
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.
646 x 567 x 969 x 930 = 330082349940
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
969 : 1, 3, 17, 19, 51, 57, 323, 969
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,567,969,930, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
567:3x 3x 3x 3x 7
969:3x 17x 19
930:2x 3x 5x 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 3x 3x 17x 19 = 5814
Therefore, the value for common factors is 5814.
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 = 330082349940/(1x5814)
LCM = 330082349940/5814
LCM = 56773710
Thus, we can understand that the LCM of 646,567,969,930 is 56773710.
