Given numbers are 645,798,309,714,127
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,798,309,714,127 is 38153221890.
Find LCM of 645,798,309,714,127 with Prime Factorization
| 2 | 645, 798, 309, 714, 127 |
| 3 | 645, 399, 309, 357, 127 |
| 7 | 215, 133, 103, 119, 127 |
| 215, 19, 103, 17, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 215 x 19 x 103 x 17 x 127 = 38153221890
Therefore, the lowest common multiple of 645,798,309,714,127 is 38153221890.
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.
645 x 798 x 309 x 714 x 127 = 14421917874420
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
309 : 1, 3, 103, 309
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
127 : 1, 127
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,798,309,714,127, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
798:2x 3x 7x 19
309:3x 103
714:2x 3x 7x 17
127:127
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 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 14421917874420/(1x378)
LCM = 14421917874420/378
LCM = 38153221890
Thus, we can understand that the LCM of 645,798,309,714,127 is 38153221890.
