The LCM of 765,658,680,974,786 is 128453983560.
Find LCM of 765,658,680,974,786 with Prime Factorization
| 2 | 765, 658, 680, 974, 786 |
| 3 | 765, 329, 340, 487, 393 |
| 5 | 255, 329, 340, 487, 131 |
| 17 | 51, 329, 68, 487, 131 |
| 3, 329, 4, 487, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 3 x 329 x 4 x 487 x 131 = 128453983560
Therefore, the lowest common multiple of 765,658,680,974,786 is 128453983560.
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.
765 x 658 x 680 x 974 x 786 = 262046126462400
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
658 : 1, 2, 7, 14, 47, 94, 329, 658
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
974 : 1, 2, 487, 974
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,658,680,974,786, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
658:2x 7x 47
680:2x 2x 2x 5x 17
974:2x 487
786:2x 3x 131
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 3x 5x 17 = 2040
Therefore, the value for common factors is 2040.
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 = 262046126462400/(1x2040)
LCM = 262046126462400/2040
LCM = 128453983560
Thus, we can understand that the LCM of 765,658,680,974,786 is 128453983560.
