Given numbers are 891,181,692,513,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,181,692,513,774 is 91176817644.
Find LCM of 891,181,692,513,774 with Prime Factorization
| 2 | 891, 181, 692, 513, 774 |
| 3 | 891, 181, 346, 513, 387 |
| 3 | 297, 181, 346, 171, 129 |
| 3 | 99, 181, 346, 57, 43 |
| 33, 181, 346, 19, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 33 x 181 x 346 x 19 x 43 = 91176817644
Therefore, the lowest common multiple of 891,181,692,513,774 is 91176817644.
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.
891 x 181 x 692 x 513 x 774 = 44311933374984
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
181 : 1, 181
692 : 1, 2, 4, 173, 346, 692
513 : 1, 3, 9, 19, 27, 57, 171, 513
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,181,692,513,774, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
181:181
692:2x 2x 173
513:3x 3x 3x 19
774:2x 3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 44311933374984/(1x486)
LCM = 44311933374984/486
LCM = 91176817644
Thus, we can understand that the LCM of 891,181,692,513,774 is 91176817644.
