Given numbers are 745,959,812,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,959,812,685 is 82876780.
Find LCM of 745,959,812,685 with Prime Factorization
| 5 | 745, 959, 812, 685 |
| 7 | 149, 959, 812, 137 |
| 137 | 149, 137, 116, 137 |
| 149, 1, 116, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 137 x 149 x 1 x 116 x 1 = 82876780
Therefore, the lowest common multiple of 745,959,812,685 is 82876780.
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.
745 x 959 x 812 x 685 = 397394160100
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.
745 : 1, 5, 149, 745
959 : 1, 7, 137, 959
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,959,812,685, is 1.
Now, the common factors can be found like this.
745:5x 149
959:7x 137
812:2x 2x 7x 29
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 137 = 4795
Therefore, the value for common factors is 4795.
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 = 397394160100/(1x4795)
LCM = 397394160100/4795
LCM = 82876780
Thus, we can understand that the LCM of 745,959,812,685 is 82876780.
