Given numbers are 914,462,671,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 914,462,671,434 is 399254394.
Find LCM of 914,462,671,434 with Prime Factorization
| 2 | 914, 462, 671, 434 |
| 7 | 457, 231, 671, 217 |
| 11 | 457, 33, 671, 31 |
| 457, 3, 61, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 457 x 3 x 61 x 31 = 399254394
Therefore, the lowest common multiple of 914,462,671,434 is 399254394.
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.
914 x 462 x 671 x 434 = 122970353352
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.
914 : 1, 2, 457, 914
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
671 : 1, 11, 61, 671
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 914,462,671,434, is 1.
Now, the common factors can be found like this.
914:2x 457
462:2x 3x 7x 11
671:11x 61
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.
2x 2x 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 122970353352/(1x308)
LCM = 122970353352/308
LCM = 399254394
Thus, we can understand that the LCM of 914,462,671,434 is 399254394.
