Given numbers are 865,121,781,103,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,121,781,103,424 is 324536021480.
Find LCM of 865,121,781,103,424 with Prime Factorization
| 11 | 865, 121, 781, 103, 424 |
| 865, 11, 71, 103, 424 |
Multiply the prime numbers at the bottom and the left side.
11 x 865 x 11 x 71 x 103 x 424 = 324536021480
Therefore, the lowest common multiple of 865,121,781,103,424 is 324536021480.
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.
865 x 121 x 781 x 103 x 424 = 3569896236280
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.
865 : 1, 5, 173, 865
121 : 1, 11, 121
781 : 1, 11, 71, 781
103 : 1, 103
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,121,781,103,424, is 1.
Now, the common factors can be found like this.
865:5x 173
121:11x 11
781:11x 71
103:103
424:2x 2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 3569896236280/(1x11)
LCM = 3569896236280/11
LCM = 324536021480
Thus, we can understand that the LCM of 865,121,781,103,424 is 324536021480.
