Given numbers are 351,981,403,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 351,981,403,436 is 4744116.
Find LCM of 351,981,403,436 with Prime Factorization
| 3 | 351, 981, 403, 436 |
| 3 | 117, 327, 403, 436 |
| 13 | 39, 109, 403, 436 |
| 109 | 3, 109, 31, 436 |
| 3, 1, 31, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 109 x 3 x 1 x 31 x 4 = 4744116
Therefore, the lowest common multiple of 351,981,403,436 is 4744116.
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.
351 x 981 x 403 x 436 = 60501711348
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
981 : 1, 3, 9, 109, 327, 981
403 : 1, 13, 31, 403
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,981,403,436, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
981:3x 3x 109
403:13x 31
436:2x 2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 109 = 12753
Therefore, the value for common factors is 12753.
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 = 60501711348/(1x12753)
LCM = 60501711348/12753
LCM = 4744116
Thus, we can understand that the LCM of 351,981,403,436 is 4744116.
