Given numbers are 606,861,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 606,861,691 is 120180102.
Find LCM of 606,861,691 with Prime Factorization
| 3 | 606, 861, 691 |
| 202, 287, 691 |
Multiply the prime numbers at the bottom and the left side.
3 x 202 x 287 x 691 = 120180102
Therefore, the lowest common multiple of 606,861,691 is 120180102.
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.
606 x 861 x 691 = 360540306
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.
606 : 1, 2, 3, 6, 101, 202, 303, 606
861 : 1, 3, 7, 21, 41, 123, 287, 861
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 606,861,691, is 1.
Now, the common factors can be found like this.
606:2x 3x 101
861:3x 7x 41
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 360540306/(1x3)
LCM = 360540306/3
LCM = 120180102
Thus, we can understand that the LCM of 606,861,691 is 120180102.
