Given numbers are 676,220,738,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,220,738,765 is 233230140.
Find LCM of 676,220,738,765 with Prime Factorization
| 2 | 676, 220, 738, 765 |
| 2 | 338, 110, 369, 765 |
| 3 | 169, 55, 369, 765 |
| 3 | 169, 55, 123, 255 |
| 5 | 169, 55, 41, 85 |
| 169, 11, 41, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 169 x 11 x 41 x 17 = 233230140
Therefore, the lowest common multiple of 676,220,738,765 is 233230140.
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.
676 x 220 x 738 x 765 = 83962850400
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,220,738,765, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
220:2x 2x 5x 11
738:2x 3x 3x 41
765:3x 3x 5x 17
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 83962850400/(1x360)
LCM = 83962850400/360
LCM = 233230140
Thus, we can understand that the LCM of 676,220,738,765 is 233230140.
