Given numbers are 538,646,807,630,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,646,807,630,561 is 602126910.
Find LCM of 538,646,807,630,561 with Prime Factorization
| 2 | 538, 646, 807, 630, 561 |
| 3 | 269, 323, 807, 315, 561 |
| 17 | 269, 323, 269, 105, 187 |
| 269 | 269, 19, 269, 105, 11 |
| 1, 19, 1, 105, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 269 x 1 x 19 x 1 x 105 x 11 = 602126910
Therefore, the lowest common multiple of 538,646,807,630,561 is 602126910.
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.
538 x 646 x 807 x 630 x 561 = 99126948939480
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.
538 : 1, 2, 269, 538
646 : 1, 2, 17, 19, 34, 38, 323, 646
807 : 1, 3, 269, 807
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,646,807,630,561, is 1.
Now, the common factors can be found like this.
538:2x 269
646:2x 17x 19
807:3x 269
630:2x 3x 3x 5x 7
561:3x 11x 17
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 3x 17x 269 = 164628
Therefore, the value for common factors is 164628.
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 = 99126948939480/(1x164628)
LCM = 99126948939480/164628
LCM = 602126910
Thus, we can understand that the LCM of 538,646,807,630,561 is 602126910.
