Given numbers are 746,682,421,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,682,421,242 is 1178061566.
Find LCM of 746,682,421,242 with Prime Factorization
| 2 | 746, 682, 421, 242 |
| 11 | 373, 341, 421, 121 |
| 373, 31, 421, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 373 x 31 x 421 x 11 = 1178061566
Therefore, the lowest common multiple of 746,682,421,242 is 1178061566.
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.
746 x 682 x 421 x 242 = 51834708904
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.
746 : 1, 2, 373, 746
682 : 1, 2, 11, 22, 31, 62, 341, 682
421 : 1, 421
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,682,421,242, is 1.
Now, the common factors can be found like this.
746:2x 373
682:2x 11x 31
421:421
242:2x 11x 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 11 = 44
Therefore, the value for common factors is 44.
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 = 51834708904/(1x44)
LCM = 51834708904/44
LCM = 1178061566
Thus, we can understand that the LCM of 746,682,421,242 is 1178061566.
