Given numbers are 564,778,380,778,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 564,778,380,778,991 is 20655036420.
Find LCM of 564,778,380,778,991 with Prime Factorization
| 2 | 564, 778, 380, 778, 991 |
| 2 | 282, 389, 190, 389, 991 |
| 389 | 141, 389, 95, 389, 991 |
| 141, 1, 95, 1, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 389 x 141 x 1 x 95 x 1 x 991 = 20655036420
Therefore, the lowest common multiple of 564,778,380,778,991 is 20655036420.
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.
564 x 778 x 380 x 778 x 991 = 128556946678080
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.
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
778 : 1, 2, 389, 778
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
778 : 1, 2, 389, 778
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,778,380,778,991, is 1.
Now, the common factors can be found like this.
564:2x 2x 3x 47
778:2x 389
380:2x 2x 5x 19
778:2x 389
991:991
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 2x 2x 389 = 6224
Therefore, the value for common factors is 6224.
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 = 128556946678080/(1x6224)
LCM = 128556946678080/6224
LCM = 20655036420
Thus, we can understand that the LCM of 564,778,380,778,991 is 20655036420.
