Given numbers are 643,778,561,959,532
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,778,561,959,532 is 10227173766348.
Find LCM of 643,778,561,959,532 with Prime Factorization
| 2 | 643, 778, 561, 959, 532 |
| 7 | 643, 389, 561, 959, 266 |
| 643, 389, 561, 137, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 643 x 389 x 561 x 137 x 38 = 10227173766348
Therefore, the lowest common multiple of 643,778,561,959,532 is 10227173766348.
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.
643 x 778 x 561 x 959 x 532 = 143180432728872
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.
643 : 1, 643
778 : 1, 2, 389, 778
561 : 1, 3, 11, 17, 33, 51, 187, 561
959 : 1, 7, 137, 959
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,778,561,959,532, is 1.
Now, the common factors can be found like this.
643:643
778:2x 389
561:3x 11x 17
959:7x 137
532:2x 2x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 143180432728872/(1x14)
LCM = 143180432728872/14
LCM = 10227173766348
Thus, we can understand that the LCM of 643,778,561,959,532 is 10227173766348.
