Find LCM of 988,189,283,858,220 with Prime Factorization
| 2 | 988, 189, 283, 858, 220 |
| 2 | 494, 189, 283, 429, 110 |
| 3 | 247, 189, 283, 429, 55 |
| 11 | 247, 63, 283, 143, 55 |
| 13 | 247, 63, 283, 13, 5 |
| 19, 63, 283, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 19 x 63 x 283 x 1 x 5 = 2906483580
Therefore, the lowest common multiple of 988,189,283,858,220 is 2906483580.
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.
988 x 189 x 283 x 858 x 220 = 9975051646560
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
189 : 1, 3, 7, 9, 21, 27, 63, 189
283 : 1, 283
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,189,283,858,220, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
189:3x 3x 3x 7
283:283
858:2x 3x 11x 13
220:2x 2x 5x 11
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 11x 13 = 3432
Therefore, the value for common factors is 3432.
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 = 9975051646560/(1x3432)
LCM = 9975051646560/3432
LCM = 2906483580
Thus, we can understand that the LCM of 988,189,283,858,220 is 2906483580.
