Find LCM of 491,525,900,400,253 with Prime Factorization
| 2 | 491, 525, 900, 400, 253 |
| 2 | 491, 525, 450, 200, 253 |
| 3 | 491, 525, 225, 100, 253 |
| 5 | 491, 175, 75, 100, 253 |
| 5 | 491, 35, 15, 20, 253 |
| 491, 7, 3, 4, 253 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 491 x 7 x 3 x 4 x 253 = 3130419600
Therefore, the lowest common multiple of 491,525,900,400,253 is 3130419600.
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.
491 x 525 x 900 x 400 x 253 = 23478147000000
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.
491 : 1, 491
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
253 : 1, 11, 23, 253
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,525,900,400,253, is 1.
Now, the common factors can be found like this.
491:491
525:3x 5x 5x 7
900:2x 2x 3x 3x 5x 5
400:2x 2x 2x 2x 5x 5
253:11x 23
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 3x 5x 5x 5x 5 = 7500
Therefore, the value for common factors is 7500.
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 = 23478147000000/(1x7500)
LCM = 23478147000000/7500
LCM = 3130419600
Thus, we can understand that the LCM of 491,525,900,400,253 is 3130419600.
