Find LCM of 988,657,663,690,610 with Prime Factorization
| 2 | 988, 657, 663, 690, 610 |
| 3 | 494, 657, 663, 345, 305 |
| 5 | 494, 219, 221, 115, 305 |
| 13 | 494, 219, 221, 23, 61 |
| 38, 219, 17, 23, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 38 x 219 x 17 x 23 x 61 = 77410328580
Therefore, the lowest common multiple of 988,657,663,690,610 is 77410328580.
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 657 x 663 x 690 x 610 = 181140168877200
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
657 : 1, 3, 9, 73, 219, 657
663 : 1, 3, 13, 17, 39, 51, 221, 663
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
610 : 1, 2, 5, 10, 61, 122, 305, 610
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,657,663,690,610, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
657:3x 3x 73
663:3x 13x 17
690:2x 3x 5x 23
610:2x 5x 61
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 3x 5x 13 = 2340
Therefore, the value for common factors is 2340.
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 = 181140168877200/(1x2340)
LCM = 181140168877200/2340
LCM = 77410328580
Thus, we can understand that the LCM of 988,657,663,690,610 is 77410328580.
