Given numbers are 899,154,399,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 899,154,399,781 is 560290962.
Find LCM of 899,154,399,781 with Prime Factorization
| 7 | 899, 154, 399, 781 |
| 11 | 899, 22, 57, 781 |
| 899, 2, 57, 71 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 899 x 2 x 57 x 71 = 560290962
Therefore, the lowest common multiple of 899,154,399,781 is 560290962.
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.
899 x 154 x 399 x 781 = 43142404074
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.
899 : 1, 29, 31, 899
154 : 1, 2, 7, 11, 14, 22, 77, 154
399 : 1, 3, 7, 19, 21, 57, 133, 399
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 899,154,399,781, is 1.
Now, the common factors can be found like this.
899:29x 31
154:2x 7x 11
399:3x 7x 19
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 43142404074/(1x77)
LCM = 43142404074/77
LCM = 560290962
Thus, we can understand that the LCM of 899,154,399,781 is 560290962.
