Find LCM of 918,988,357,663 with Prime Factorization
| 2 | 918, 988, 357, 663 |
| 3 | 459, 494, 357, 663 |
| 13 | 153, 494, 119, 221 |
| 17 | 153, 38, 119, 17 |
| 9, 38, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 9 x 38 x 7 x 1 = 3174444
Therefore, the lowest common multiple of 918,988,357,663 is 3174444.
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.
918 x 988 x 357 x 663 = 214674949944
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
357 : 1, 3, 7, 17, 21, 51, 119, 357
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,988,357,663, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
988:2x 2x 13x 19
357:3x 7x 17
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13x 17x 17 = 67626
Therefore, the value for common factors is 67626.
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 = 214674949944/(1x67626)
LCM = 214674949944/67626
LCM = 3174444
Thus, we can understand that the LCM of 918,988,357,663 is 3174444.
