Given numbers are 668,377,793,254,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,377,793,254,638 is 21460708412.
Find LCM of 668,377,793,254,638 with Prime Factorization
| 2 | 668, 377, 793, 254, 638 |
| 13 | 334, 377, 793, 127, 319 |
| 29 | 334, 29, 61, 127, 319 |
| 334, 1, 61, 127, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 334 x 1 x 61 x 127 x 11 = 21460708412
Therefore, the lowest common multiple of 668,377,793,254,638 is 21460708412.
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.
668 x 377 x 793 x 254 x 638 = 32362748285296
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.
668 : 1, 2, 4, 167, 334, 668
377 : 1, 13, 29, 377
793 : 1, 13, 61, 793
254 : 1, 2, 127, 254
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,377,793,254,638, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
377:13x 29
793:13x 61
254:2x 127
638:2x 11x 29
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 13x 29 = 1508
Therefore, the value for common factors is 1508.
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 = 32362748285296/(1x1508)
LCM = 32362748285296/1508
LCM = 21460708412
Thus, we can understand that the LCM of 668,377,793,254,638 is 21460708412.
