Given numbers are 853,140,817,308,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,140,817,308,388 is 104103071380.
Find LCM of 853,140,817,308,388 with Prime Factorization
| 2 | 853, 140, 817, 308, 388 |
| 2 | 853, 70, 817, 154, 194 |
| 7 | 853, 35, 817, 77, 97 |
| 853, 5, 817, 11, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 853 x 5 x 817 x 11 x 97 = 104103071380
Therefore, the lowest common multiple of 853,140,817,308,388 is 104103071380.
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.
853 x 140 x 817 x 308 x 388 = 11659543994560
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.
853 : 1, 853
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
817 : 1, 19, 43, 817
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,140,817,308,388, is 1.
Now, the common factors can be found like this.
853:853
140:2x 2x 5x 7
817:19x 43
308:2x 2x 7x 11
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 11659543994560/(1x112)
LCM = 11659543994560/112
LCM = 104103071380
Thus, we can understand that the LCM of 853,140,817,308,388 is 104103071380.
