Given numbers are 865,539,138,253
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,539,138,253 is 64340430.
Find LCM of 865,539,138,253 with Prime Factorization
| 11 | 865, 539, 138, 253 |
| 23 | 865, 49, 138, 23 |
| 865, 49, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 865 x 49 x 6 x 1 = 64340430
Therefore, the lowest common multiple of 865,539,138,253 is 64340430.
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 539 x 138 x 253 = 16278128790
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
539 : 1, 7, 11, 49, 77, 539
138 : 1, 2, 3, 6, 23, 46, 69, 138
253 : 1, 11, 23, 253
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,539,138,253, is 1.
Now, the common factors can be found like this.
865:5x 173
539:7x 7x 11
138:2x 3x 23
253:11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23 = 253
Therefore, the value for common factors is 253.
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 = 16278128790/(1x253)
LCM = 16278128790/253
LCM = 64340430
Thus, we can understand that the LCM of 865,539,138,253 is 64340430.
