Given numbers are 615,541,989,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,541,989,666 is 73050239970.
Find LCM of 615,541,989,666 with Prime Factorization
| 3 | 615, 541, 989, 666 |
| 205, 541, 989, 222 |
Multiply the prime numbers at the bottom and the left side.
3 x 205 x 541 x 989 x 222 = 73050239970
Therefore, the lowest common multiple of 615,541,989,666 is 73050239970.
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.
615 x 541 x 989 x 666 = 219150719910
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
541 : 1, 541
989 : 1, 23, 43, 989
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,541,989,666, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
541:541
989:23x 43
666:2x 3x 3x 37
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 = 219150719910/(1x3)
LCM = 219150719910/3
LCM = 73050239970
Thus, we can understand that the LCM of 615,541,989,666 is 73050239970.
