The LCM of 865,191,370,138,666 is 2530763370.
Find LCM of 865,191,370,138,666 with Prime Factorization
| 2 | 865, 191, 370, 138, 666 |
| 3 | 865, 191, 185, 69, 333 |
| 5 | 865, 191, 185, 23, 111 |
| 37 | 173, 191, 37, 23, 111 |
| 173, 191, 1, 23, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 173 x 191 x 1 x 23 x 3 = 2530763370
Therefore, the lowest common multiple of 865,191,370,138,666 is 2530763370.
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 191 x 370 x 138 x 666 = 5618294681400
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
191 : 1, 191
370 : 1, 2, 5, 10, 37, 74, 185, 370
138 : 1, 2, 3, 6, 23, 46, 69, 138
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,191,370,138,666, is 1.
Now, the common factors can be found like this.
865:5x 173
191:191
370:2x 5x 37
138:2x 3x 23
666:2x 3x 3x 37
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 3x 5x 37 = 2220
Therefore, the value for common factors is 2220.
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 = 5618294681400/(1x2220)
LCM = 5618294681400/2220
LCM = 2530763370
Thus, we can understand that the LCM of 865,191,370,138,666 is 2530763370.
