Given numbers are 187,765,638,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,765,638,790 is 38557530.
Find LCM of 187,765,638,790 with Prime Factorization
| 2 | 187, 765, 638, 790 |
| 5 | 187, 765, 319, 395 |
| 11 | 187, 153, 319, 79 |
| 17 | 17, 153, 29, 79 |
| 1, 9, 29, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 17 x 1 x 9 x 29 x 79 = 38557530
Therefore, the lowest common multiple of 187,765,638,790 is 38557530.
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.
187 x 765 x 638 x 790 = 72102581100
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.
187 : 1, 11, 17, 187
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
638 : 1, 2, 11, 22, 29, 58, 319, 638
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,765,638,790, is 1.
Now, the common factors can be found like this.
187:11x 17
765:3x 3x 5x 17
638:2x 11x 29
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 17 = 1870
Therefore, the value for common factors is 1870.
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 = 72102581100/(1x1870)
LCM = 72102581100/1870
LCM = 38557530
Thus, we can understand that the LCM of 187,765,638,790 is 38557530.
