Find LCM of 142,704,525,676,720 with Prime Factorization
| 2 | 142, 704, 525, 676, 720 |
| 2 | 71, 352, 525, 338, 360 |
| 2 | 71, 176, 525, 169, 180 |
| 2 | 71, 88, 525, 169, 90 |
| 3 | 71, 44, 525, 169, 45 |
| 5 | 71, 44, 175, 169, 15 |
| 71, 44, 35, 169, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 71 x 44 x 35 x 169 x 3 = 13304491200
Therefore, the lowest common multiple of 142,704,525,676,720 is 13304491200.
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.
142 x 704 x 525 x 676 x 720 = 25544623104000
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.
142 : 1, 2, 71, 142
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,704,525,676,720, is 1.
Now, the common factors can be found like this.
142:2x 71
704:2x 2x 2x 2x 2x 2x 11
525:3x 5x 5x 7
676:2x 2x 13x 13
720:2x 2x 2x 2x 3x 3x 5
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 2x 2x 2x 2x 2x 3x 5 = 1920
Therefore, the value for common factors is 1920.
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 = 25544623104000/(1x1920)
LCM = 25544623104000/1920
LCM = 13304491200
Thus, we can understand that the LCM of 142,704,525,676,720 is 13304491200.
