Find LCM of 761,978,800,576 with Prime Factorization
| 2 | 761, 978, 800, 576 |
| 2 | 761, 489, 400, 288 |
| 2 | 761, 489, 200, 144 |
| 2 | 761, 489, 100, 72 |
| 2 | 761, 489, 50, 36 |
| 3 | 761, 489, 25, 18 |
| 761, 163, 25, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 761 x 163 x 25 x 6 = 1786219200
Therefore, the lowest common multiple of 761,978,800,576 is 1786219200.
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.
761 x 978 x 800 x 576 = 342954086400
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.
761 : 1, 761
978 : 1, 2, 3, 6, 163, 326, 489, 978
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,978,800,576, is 1.
Now, the common factors can be found like this.
761:761
978:2x 3x 163
800:2x 2x 2x 2x 2x 5x 5
576:2x 2x 2x 2x 2x 2x 3x 3
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 342954086400/(1x192)
LCM = 342954086400/192
LCM = 1786219200
Thus, we can understand that the LCM of 761,978,800,576 is 1786219200.
