Given numbers are 322,754,474,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 322,754,474,870 is 143851890.
Find LCM of 322,754,474,870 with Prime Factorization
| 2 | 322, 754, 474, 870 |
| 3 | 161, 377, 237, 435 |
| 29 | 161, 377, 79, 145 |
| 161, 13, 79, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 161 x 13 x 79 x 5 = 143851890
Therefore, the lowest common multiple of 322,754,474,870 is 143851890.
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.
322 x 754 x 474 x 870 = 100120915440
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.
322 : 1, 2, 7, 14, 23, 46, 161, 322
754 : 1, 2, 13, 26, 29, 58, 377, 754
474 : 1, 2, 3, 6, 79, 158, 237, 474
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,754,474,870, is 2.
Now, the common factors can be found like this.
322:2x 7x 23
754:2x 13x 29
474:2x 3x 79
870:2x 3x 5x 29
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 29 = 348
Therefore, the value for common factors is 348.
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 = 100120915440/(2x348)
LCM = 100120915440/696
LCM = 143851890
Thus, we can understand that the LCM of 322,754,474,870 is 143851890.
