Given numbers are 820,918,161,714
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,918,161,714 is 60597180.
Find LCM of 820,918,161,714 with Prime Factorization
| 2 | 820, 918, 161, 714 |
| 3 | 410, 459, 161, 357 |
| 7 | 410, 153, 161, 119 |
| 17 | 410, 153, 23, 17 |
| 410, 9, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 410 x 9 x 23 x 1 = 60597180
Therefore, the lowest common multiple of 820,918,161,714 is 60597180.
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.
820 x 918 x 161 x 714 = 86532773040
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
161 : 1, 7, 23, 161
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,918,161,714, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
918:2x 3x 3x 3x 17
161:7x 23
714:2x 3x 7x 17
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 7x 17 = 1428
Therefore, the value for common factors is 1428.
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 = 86532773040/(1x1428)
LCM = 86532773040/1428
LCM = 60597180
Thus, we can understand that the LCM of 820,918,161,714 is 60597180.
