Given numbers are 106,389,421,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 106,389,421,428 is 3714935996.
Find LCM of 106,389,421,428 with Prime Factorization
| 2 | 106, 389, 421, 428 |
| 53, 389, 421, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 389 x 421 x 214 = 3714935996
Therefore, the lowest common multiple of 106,389,421,428 is 3714935996.
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.
106 x 389 x 421 x 428 = 7429871992
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.
106 : 1, 2, 53, 106
389 : 1, 389
421 : 1, 421
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 106,389,421,428, is 1.
Now, the common factors can be found like this.
106:2x 53
389:389
421:421
428:2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 7429871992/(1x2)
LCM = 7429871992/2
LCM = 3714935996
Thus, we can understand that the LCM of 106,389,421,428 is 3714935996.
