Given numbers are 421,744,874,421,488
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,744,874,421,488 is 8349612168.
Find LCM of 421,744,874,421,488 with Prime Factorization
| 2 | 421, 744, 874, 421, 488 |
| 2 | 421, 372, 437, 421, 244 |
| 2 | 421, 186, 437, 421, 122 |
| 421 | 421, 93, 437, 421, 61 |
| 1, 93, 437, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 421 x 1 x 93 x 437 x 1 x 61 = 8349612168
Therefore, the lowest common multiple of 421,744,874,421,488 is 8349612168.
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.
421 x 744 x 874 x 421 x 488 = 56242987563648
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.
421 : 1, 421
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
874 : 1, 2, 19, 23, 38, 46, 437, 874
421 : 1, 421
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,744,874,421,488, is 1.
Now, the common factors can be found like this.
421:421
744:2x 2x 2x 3x 31
874:2x 19x 23
421:421
488:2x 2x 2x 61
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 2x 421 = 6736
Therefore, the value for common factors is 6736.
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 = 56242987563648/(1x6736)
LCM = 56242987563648/6736
LCM = 8349612168
Thus, we can understand that the LCM of 421,744,874,421,488 is 8349612168.
