Given numbers are 442,706,421,338,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,706,421,338,462 is 197257898838.
Find LCM of 442,706,421,338,462 with Prime Factorization
| 2 | 442, 706, 421, 338, 462 |
| 13 | 221, 353, 421, 169, 231 |
| 17, 353, 421, 13, 231 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 353 x 421 x 13 x 231 = 197257898838
Therefore, the lowest common multiple of 442,706,421,338,462 is 197257898838.
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.
442 x 706 x 421 x 338 x 462 = 20514821479152
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
706 : 1, 2, 353, 706
421 : 1, 421
338 : 1, 2, 13, 26, 169, 338
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,706,421,338,462, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
706:2x 353
421:421
338:2x 13x 13
462:2x 3x 7x 11
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 13 = 104
Therefore, the value for common factors is 104.
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 = 20514821479152/(1x104)
LCM = 20514821479152/104
LCM = 197257898838
Thus, we can understand that the LCM of 442,706,421,338,462 is 197257898838.
