Find LCM of 750,675,513,665,978 with Prime Factorization
| 2 | 750, 675, 513, 665, 978 |
| 3 | 375, 675, 513, 665, 489 |
| 3 | 125, 225, 171, 665, 163 |
| 3 | 125, 75, 57, 665, 163 |
| 5 | 125, 25, 19, 665, 163 |
| 5 | 5, 25, 19, 133, 163 |
| 19 | 1, 5, 19, 133, 163 |
| 1, 5, 1, 7, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 5 x 19 x 1 x 5 x 1 x 7 x 163 = 146333250
Therefore, the lowest common multiple of 750,675,513,665,978 is 146333250.
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.
750 x 675 x 513 x 665 x 978 = 168905153812500
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.
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
513 : 1, 3, 9, 19, 27, 57, 171, 513
665 : 1, 5, 7, 19, 35, 95, 133, 665
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 750,675,513,665,978, is 1.
Now, the common factors can be found like this.
750:2x 3x 5x 5x 5
675:3x 3x 3x 5x 5
513:3x 3x 3x 19
665:5x 7x 19
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 3x 3x 3x 3x 3x 5x 5x 5x 19 = 1154250
Therefore, the value for common factors is 1154250.
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 = 168905153812500/(1x1154250)
LCM = 168905153812500/1154250
LCM = 146333250
Thus, we can understand that the LCM of 750,675,513,665,978 is 146333250.
