Given numbers are 781,171,893,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,171,893,923 is 81599661.
Find LCM of 781,171,893,923 with Prime Factorization
19 | 781, 171, 893, 923 |
71 | 781, 9, 47, 923 |
11, 9, 47, 13 |
Multiply the prime numbers at the bottom and the left side.
19 x 71 x 11 x 9 x 47 x 13 = 81599661
Therefore, the lowest common multiple of 781,171,893,923 is 81599661.
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.
781 x 171 x 893 x 923 = 110077942689
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.
781 : 1, 11, 71, 781
171 : 1, 3, 9, 19, 57, 171
893 : 1, 19, 47, 893
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,171,893,923, is 1.
Now, the common factors can be found like this.
781:11x 71
171:3x 3x 19
893:19x 47
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 71 = 1349
Therefore, the value for common factors is 1349.
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 = 110077942689/(1x1349)
LCM = 110077942689/1349
LCM = 81599661
Thus, we can understand that the LCM of 781,171,893,923 is 81599661.
