Given numbers are 527,663,420,907
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 527,663,420,907 is 2609819940.
Find LCM of 527,663,420,907 with Prime Factorization
| 3 | 527, 663, 420, 907 |
| 17 | 527, 221, 140, 907 |
| 31, 13, 140, 907 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 31 x 13 x 140 x 907 = 2609819940
Therefore, the lowest common multiple of 527,663,420,907 is 2609819940.
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.
527 x 663 x 420 x 907 = 133100816940
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.
527 : 1, 17, 31, 527
663 : 1, 3, 13, 17, 39, 51, 221, 663
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
907 : 1, 907
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 527,663,420,907, is 1.
Now, the common factors can be found like this.
527:17x 31
663:3x 13x 17
420:2x 2x 3x 5x 7
907:907
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 133100816940/(1x51)
LCM = 133100816940/51
LCM = 2609819940
Thus, we can understand that the LCM of 527,663,420,907 is 2609819940.
