Given numbers are 318,403,689,461
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,403,689,461 is 59078994.
Find LCM of 318,403,689,461 with Prime Factorization
| 13 | 318, 403, 689, 461 |
| 53 | 318, 31, 53, 461 |
| 6, 31, 1, 461 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 6 x 31 x 1 x 461 = 59078994
Therefore, the lowest common multiple of 318,403,689,461 is 59078994.
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 403 x 689 x 461 = 40705426866
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
403 : 1, 13, 31, 403
689 : 1, 13, 53, 689
461 : 1, 461
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,403,689,461, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
403:13x 31
689:13x 53
461:461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 53 = 689
Therefore, the value for common factors is 689.
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 = 40705426866/(1x689)
LCM = 40705426866/689
LCM = 59078994
Thus, we can understand that the LCM of 318,403,689,461 is 59078994.
