Find LCM of 665,784,524,608 with Prime Factorization
| 2 | 665, 784, 524, 608 |
| 2 | 665, 392, 262, 304 |
| 2 | 665, 196, 131, 152 |
| 2 | 665, 98, 131, 76 |
| 7 | 665, 49, 131, 38 |
| 19 | 95, 7, 131, 38 |
| 5, 7, 131, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 19 x 5 x 7 x 131 x 2 = 19513760
Therefore, the lowest common multiple of 665,784,524,608 is 19513760.
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.
665 x 784 x 524 x 608 = 166101125120
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
524 : 1, 2, 4, 131, 262, 524
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,784,524,608, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
784:2x 2x 2x 2x 7x 7
524:2x 2x 131
608:2x 2x 2x 2x 2x 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 2x 2x 2x 2x 7x 19 = 8512
Therefore, the value for common factors is 8512.
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 = 166101125120/(1x8512)
LCM = 166101125120/8512
LCM = 19513760
Thus, we can understand that the LCM of 665,784,524,608 is 19513760.
