Given numbers are 691,741,807,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,741,807,342 is 826418034.
Find LCM of 691,741,807,342 with Prime Factorization
| 3 | 691, 741, 807, 342 |
| 19 | 691, 247, 269, 114 |
| 691, 13, 269, 6 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 691 x 13 x 269 x 6 = 826418034
Therefore, the lowest common multiple of 691,741,807,342 is 826418034.
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.
691 x 741 x 807 x 342 = 141317483814
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.
691 : 1, 691
741 : 1, 3, 13, 19, 39, 57, 247, 741
807 : 1, 3, 269, 807
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,741,807,342, is 1.
Now, the common factors can be found like this.
691:691
741:3x 13x 19
807:3x 269
342:2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 141317483814/(1x171)
LCM = 141317483814/171
LCM = 826418034
Thus, we can understand that the LCM of 691,741,807,342 is 826418034.
