Given numbers are 507,676,905,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,676,905,357 is 218405460.
Find LCM of 507,676,905,357 with Prime Factorization
| 3 | 507, 676, 905, 357 |
| 13 | 169, 676, 905, 119 |
| 13 | 13, 52, 905, 119 |
| 1, 4, 905, 119 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 13 x 1 x 4 x 905 x 119 = 218405460
Therefore, the lowest common multiple of 507,676,905,357 is 218405460.
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.
507 x 676 x 905 x 357 = 110731568220
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.
507 : 1, 3, 13, 39, 169, 507
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
905 : 1, 5, 181, 905
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,676,905,357, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
676:2x 2x 13x 13
905:5x 181
357:3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13 = 507
Therefore, the value for common factors is 507.
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 = 110731568220/(1x507)
LCM = 110731568220/507
LCM = 218405460
Thus, we can understand that the LCM of 507,676,905,357 is 218405460.
