Given numbers are 750,785,391,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 750,785,391,330 is 506442750.
Find LCM of 750,785,391,330 with Prime Factorization
| 2 | 750, 785, 391, 330 |
| 3 | 375, 785, 391, 165 |
| 5 | 125, 785, 391, 55 |
| 25, 157, 391, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 25 x 157 x 391 x 11 = 506442750
Therefore, the lowest common multiple of 750,785,391,330 is 506442750.
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 785 x 391 x 330 = 75966412500
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
785 : 1, 5, 157, 785
391 : 1, 17, 23, 391
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 750,785,391,330, is 1.
Now, the common factors can be found like this.
750:2x 3x 5x 5x 5
785:5x 157
391:17x 23
330:2x 3x 5x 11
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 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 75966412500/(1x150)
LCM = 75966412500/150
LCM = 506442750
Thus, we can understand that the LCM of 750,785,391,330 is 506442750.
