Given numbers are 344,646,532,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 344,646,532,922 is 358558424.
Find LCM of 344,646,532,922 with Prime Factorization
| 2 | 344, 646, 532, 922 |
| 2 | 172, 323, 266, 461 |
| 19 | 86, 323, 133, 461 |
| 86, 17, 7, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 86 x 17 x 7 x 461 = 358558424
Therefore, the lowest common multiple of 344,646,532,922 is 358558424.
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.
344 x 646 x 532 x 922 = 109001760896
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.
344 : 1, 2, 4, 8, 43, 86, 172, 344
646 : 1, 2, 17, 19, 34, 38, 323, 646
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
922 : 1, 2, 461, 922
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,646,532,922, is 2.
Now, the common factors can be found like this.
344:2x 2x 2x 43
646:2x 17x 19
532:2x 2x 7x 19
922:2x 461
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 2x 19 = 152
Therefore, the value for common factors is 152.
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 = 109001760896/(2x152)
LCM = 109001760896/304
LCM = 358558424
Thus, we can understand that the LCM of 344,646,532,922 is 358558424.
