Find LCM of 490,676,535,252,312 with Prime Factorization
| 2 | 490, 676, 535, 252, 312 |
| 2 | 245, 338, 535, 126, 156 |
| 3 | 245, 169, 535, 63, 78 |
| 5 | 245, 169, 535, 21, 26 |
| 7 | 49, 169, 107, 21, 26 |
| 13 | 7, 169, 107, 3, 26 |
| 7, 13, 107, 3, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 7 x 13 x 107 x 3 x 2 = 318984120
Therefore, the lowest common multiple of 490,676,535,252,312 is 318984120.
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.
490 x 676 x 535 x 252 x 312 = 13933226361600
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
535 : 1, 5, 107, 535
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,676,535,252,312, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
676:2x 2x 13x 13
535:5x 107
252:2x 2x 3x 3x 7
312:2x 2x 2x 3x 13
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 3x 5x 7x 13 = 43680
Therefore, the value for common factors is 43680.
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 = 13933226361600/(1x43680)
LCM = 13933226361600/43680
LCM = 318984120
Thus, we can understand that the LCM of 490,676,535,252,312 is 318984120.
