Given numbers are 455,547,759,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,547,759,434 is 11712030330.
Find LCM of 455,547,759,434 with Prime Factorization
| 7 | 455, 547, 759, 434 |
| 65, 547, 759, 62 |
Multiply the prime numbers at the bottom and the left side.
7 x 65 x 547 x 759 x 62 = 11712030330
Therefore, the lowest common multiple of 455,547,759,434 is 11712030330.
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.
455 x 547 x 759 x 434 = 81984212310
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
547 : 1, 547
759 : 1, 3, 11, 23, 33, 69, 253, 759
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,547,759,434, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
547:547
759:3x 11x 23
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 81984212310/(1x7)
LCM = 81984212310/7
LCM = 11712030330
Thus, we can understand that the LCM of 455,547,759,434 is 11712030330.
