Given numbers are 687,722,171,962,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,722,171,962,695 is 497445000390.
Find LCM of 687,722,171,962,695 with Prime Factorization
| 2 | 687, 722, 171, 962, 695 |
| 3 | 687, 361, 171, 481, 695 |
| 19 | 229, 361, 57, 481, 695 |
| 229, 19, 3, 481, 695 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 229 x 19 x 3 x 481 x 695 = 497445000390
Therefore, the lowest common multiple of 687,722,171,962,695 is 497445000390.
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.
687 x 722 x 171 x 962 x 695 = 56708730044460
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.
687 : 1, 3, 229, 687
722 : 1, 2, 19, 38, 361, 722
171 : 1, 3, 9, 19, 57, 171
962 : 1, 2, 13, 26, 37, 74, 481, 962
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,722,171,962,695, is 1.
Now, the common factors can be found like this.
687:3x 229
722:2x 19x 19
171:3x 3x 19
962:2x 13x 37
695:5x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 56708730044460/(1x114)
LCM = 56708730044460/114
LCM = 497445000390
Thus, we can understand that the LCM of 687,722,171,962,695 is 497445000390.
