Given numbers are 186,638,770,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 186,638,770,355 is 147444990.
Find LCM of 186,638,770,355 with Prime Factorization
| 2 | 186, 638, 770, 355 |
| 5 | 93, 319, 385, 355 |
| 11 | 93, 319, 77, 71 |
| 93, 29, 7, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 93 x 29 x 7 x 71 = 147444990
Therefore, the lowest common multiple of 186,638,770,355 is 147444990.
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.
186 x 638 x 770 x 355 = 32437897800
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.
186 : 1, 2, 3, 6, 31, 62, 93, 186
638 : 1, 2, 11, 22, 29, 58, 319, 638
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,638,770,355, is 1.
Now, the common factors can be found like this.
186:2x 3x 31
638:2x 11x 29
770:2x 5x 7x 11
355:5x 71
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 32437897800/(1x220)
LCM = 32437897800/220
LCM = 147444990
Thus, we can understand that the LCM of 186,638,770,355 is 147444990.
