Find LCM of 882,686,720,738,978 with Prime Factorization
| 2 | 882, 686, 720, 738, 978 |
| 3 | 441, 343, 360, 369, 489 |
| 3 | 147, 343, 120, 123, 163 |
| 7 | 49, 343, 40, 41, 163 |
| 7 | 7, 49, 40, 41, 163 |
| 1, 7, 40, 41, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 7 x 1 x 7 x 40 x 41 x 163 = 1650433680
Therefore, the lowest common multiple of 882,686,720,738,978 is 1650433680.
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.
882 x 686 x 720 x 738 x 978 = 314427421244160
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
686 : 1, 2, 7, 14, 49, 98, 343, 686
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
978 : 1, 2, 3, 6, 163, 326, 489, 978
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,686,720,738,978, is 2.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
686:2x 7x 7x 7
720:2x 2x 2x 2x 3x 3x 5
738:2x 3x 3x 41
978:2x 3x 163
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 7x 7 = 95256
Therefore, the value for common factors is 95256.
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 = 314427421244160/(2x95256)
LCM = 314427421244160/190512
LCM = 1650433680
Thus, we can understand that the LCM of 882,686,720,738,978 is 1650433680.
