Given numbers are 902,913,451,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,913,451,728 is 27251224.
Find LCM of 902,913,451,728 with Prime Factorization
| 2 | 902, 913, 451, 728 |
| 11 | 451, 913, 451, 364 |
| 41 | 41, 83, 41, 364 |
| 1, 83, 1, 364 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 1 x 83 x 1 x 364 = 27251224
Therefore, the lowest common multiple of 902,913,451,728 is 27251224.
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 913 x 451 x 728 = 270386644528
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
913 : 1, 11, 83, 913
451 : 1, 11, 41, 451
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,913,451,728, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
913:11x 83
451:11x 41
728:2x 2x 2x 7x 13
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 11x 41 = 9922
Therefore, the value for common factors is 9922.
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 = 270386644528/(1x9922)
LCM = 270386644528/9922
LCM = 27251224
Thus, we can understand that the LCM of 902,913,451,728 is 27251224.
