Given numbers are 615,735,765,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,735,765,149 is 228995865.
Find LCM of 615,735,765,149 with Prime Factorization
| 3 | 615, 735, 765, 149 |
| 5 | 205, 245, 255, 149 |
| 41, 49, 51, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 41 x 49 x 51 x 149 = 228995865
Therefore, the lowest common multiple of 615,735,765,149 is 228995865.
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 735 x 765 x 149 = 51524069625
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
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,735,765,149, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
735:3x 5x 7x 7
765:3x 3x 5x 17
149:149
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 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 51524069625/(1x225)
LCM = 51524069625/225
LCM = 228995865
Thus, we can understand that the LCM of 615,735,765,149 is 228995865.
