Find LCM of 630,180,978,882,874 with Prime Factorization
| 2 | 630, 180, 978, 882, 874 |
| 3 | 315, 90, 489, 441, 437 |
| 3 | 105, 30, 163, 147, 437 |
| 5 | 35, 10, 163, 49, 437 |
| 7 | 7, 2, 163, 49, 437 |
| 1, 2, 163, 7, 437 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 1 x 2 x 163 x 7 x 437 = 628257420
Therefore, the lowest common multiple of 630,180,978,882,874 is 628257420.
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.
630 x 180 x 978 x 882 x 874 = 85493269713600
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
978 : 1, 2, 3, 6, 163, 326, 489, 978
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
874 : 1, 2, 19, 23, 38, 46, 437, 874
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,180,978,882,874, is 2.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
180:2x 2x 3x 3x 5
978:2x 3x 163
882:2x 3x 3x 7x 7
874:2x 19x 23
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 3x 3x 3x 5x 7 = 68040
Therefore, the value for common factors is 68040.
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 = 85493269713600/(2x68040)
LCM = 85493269713600/136080
LCM = 628257420
Thus, we can understand that the LCM of 630,180,978,882,874 is 628257420.
