Given numbers are 902,407,386,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,407,386,123 is 19323546.
Find LCM of 902,407,386,123 with Prime Factorization
| 2 | 902, 407, 386, 123 |
| 11 | 451, 407, 193, 123 |
| 41 | 41, 37, 193, 123 |
| 1, 37, 193, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 1 x 37 x 193 x 3 = 19323546
Therefore, the lowest common multiple of 902,407,386,123 is 19323546.
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.
902 x 407 x 386 x 123 = 17429838492
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
407 : 1, 11, 37, 407
386 : 1, 2, 193, 386
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,407,386,123, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
407:11x 37
386:2x 193
123:3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 41 = 902
Therefore, the value for common factors is 902.
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 = 17429838492/(1x902)
LCM = 17429838492/902
LCM = 19323546
Thus, we can understand that the LCM of 902,407,386,123 is 19323546.
