Find LCM of 525,855,665,494 with Prime Factorization
| 3 | 525, 855, 665, 494 |
| 5 | 175, 285, 665, 494 |
| 7 | 35, 57, 133, 494 |
| 19 | 5, 57, 19, 494 |
| 5, 3, 1, 26 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 19 x 5 x 3 x 1 x 26 = 778050
Therefore, the lowest common multiple of 525,855,665,494 is 778050.
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.
525 x 855 x 665 x 494 = 147459926250
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
665 : 1, 5, 7, 19, 35, 95, 133, 665
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,855,665,494, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
855:3x 3x 5x 19
665:5x 7x 19
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7x 19x 19 = 189525
Therefore, the value for common factors is 189525.
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 = 147459926250/(1x189525)
LCM = 147459926250/189525
LCM = 778050
Thus, we can understand that the LCM of 525,855,665,494 is 778050.
