Given numbers are 318,406,870,977
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,406,870,977 is 315346290.
Find LCM of 318,406,870,977 with Prime Factorization
| 2 | 318, 406, 870, 977 |
| 3 | 159, 203, 435, 977 |
| 29 | 53, 203, 145, 977 |
| 53, 7, 5, 977 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 53 x 7 x 5 x 977 = 315346290
Therefore, the lowest common multiple of 318,406,870,977 is 315346290.
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.
318 x 406 x 870 x 977 = 109740508920
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
406 : 1, 2, 7, 14, 29, 58, 203, 406
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
977 : 1, 977
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,406,870,977, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
406:2x 7x 29
870:2x 3x 5x 29
977:977
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 = 109740508920/(1x348)
LCM = 109740508920/348
LCM = 315346290
Thus, we can understand that the LCM of 318,406,870,977 is 315346290.
