Find LCM of 978,988,984,507,223 with Prime Factorization
| 2 | 978, 988, 984, 507, 223 |
| 2 | 489, 494, 492, 507, 223 |
| 3 | 489, 247, 246, 507, 223 |
| 13 | 163, 247, 82, 169, 223 |
| 163, 19, 82, 13, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 163 x 19 x 82 x 13 x 223 = 114849172776
Therefore, the lowest common multiple of 978,988,984,507,223 is 114849172776.
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.
978 x 988 x 984 x 507 x 223 = 107498825718336
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
507 : 1, 3, 13, 39, 169, 507
223 : 1, 223
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,988,984,507,223, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
988:2x 2x 13x 19
984:2x 2x 2x 3x 41
507:3x 13x 13
223:223
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 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 107498825718336/(1x936)
LCM = 107498825718336/936
LCM = 114849172776
Thus, we can understand that the LCM of 978,988,984,507,223 is 114849172776.
