Find LCM of 175,540,491,750,783 with Prime Factorization
| 2 | 175, 540, 491, 750, 783 |
| 3 | 175, 270, 491, 375, 783 |
| 3 | 175, 90, 491, 125, 261 |
| 3 | 175, 30, 491, 125, 87 |
| 5 | 175, 10, 491, 125, 29 |
| 5 | 35, 2, 491, 25, 29 |
| 7, 2, 491, 5, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 5 x 7 x 2 x 491 x 5 x 29 = 1345585500
Therefore, the lowest common multiple of 175,540,491,750,783 is 1345585500.
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.
175 x 540 x 491 x 750 x 783 = 27248106375000
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.
175 : 1, 5, 7, 25, 35, 175
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
491 : 1, 491
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 175,540,491,750,783, is 1.
Now, the common factors can be found like this.
175:5x 5x 7
540:2x 2x 3x 3x 3x 5
491:491
750:2x 3x 5x 5x 5
783:3x 3x 3x 29
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 5x 5x 5 = 20250
Therefore, the value for common factors is 20250.
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 = 27248106375000/(1x20250)
LCM = 27248106375000/20250
LCM = 1345585500
Thus, we can understand that the LCM of 175,540,491,750,783 is 1345585500.
