Find LCM of 980,123,231,817,988 with Prime Factorization
| 2 | 980, 123, 231, 817, 988 |
| 2 | 490, 123, 231, 817, 494 |
| 3 | 245, 123, 231, 817, 247 |
| 7 | 245, 41, 77, 817, 247 |
| 19 | 35, 41, 11, 817, 247 |
| 35, 41, 11, 43, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 35 x 41 x 11 x 43 x 13 = 14082808740
Therefore, the lowest common multiple of 980,123,231,817,988 is 14082808740.
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.
980 x 123 x 231 x 817 x 988 = 22476162749040
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
123 : 1, 3, 41, 123
231 : 1, 3, 7, 11, 21, 33, 77, 231
817 : 1, 19, 43, 817
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,123,231,817,988, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
123:3x 41
231:3x 7x 11
817:19x 43
988:2x 2x 13x 19
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 7x 19 = 1596
Therefore, the value for common factors is 1596.
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 = 22476162749040/(1x1596)
LCM = 22476162749040/1596
LCM = 14082808740
Thus, we can understand that the LCM of 980,123,231,817,988 is 14082808740.
