Find LCM of 100,988,217,858,777 with Prime Factorization
| 2 | 100, 988, 217, 858, 777 |
| 2 | 50, 494, 217, 429, 777 |
| 3 | 25, 247, 217, 429, 777 |
| 7 | 25, 247, 217, 143, 259 |
| 13 | 25, 247, 31, 143, 37 |
| 25, 19, 31, 11, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 25 x 19 x 31 x 11 x 37 = 6544437900
Therefore, the lowest common multiple of 100,988,217,858,777 is 6544437900.
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.
100 x 988 x 217 x 858 x 777 = 14293052373600
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
217 : 1, 7, 31, 217
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,988,217,858,777, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
988:2x 2x 13x 19
217:7x 31
858:2x 3x 11x 13
777:3x 7x 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 2x 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 14293052373600/(1x2184)
LCM = 14293052373600/2184
LCM = 6544437900
Thus, we can understand that the LCM of 100,988,217,858,777 is 6544437900.
