Given numbers are 36,21,74,66,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 36,21,74,66,616 is 205128.
Find LCM of 36,21,74,66,616 with Prime Factorization
| 2 | 36, 21, 74, 66, 616 |
| 2 | 18, 21, 37, 33, 308 |
| 3 | 9, 21, 37, 33, 154 |
| 7 | 3, 7, 37, 11, 154 |
| 11 | 3, 1, 37, 11, 22 |
| 3, 1, 37, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 3 x 1 x 37 x 1 x 2 = 205128
Therefore, the lowest common multiple of 36,21,74,66,616 is 205128.
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.
36 x 21 x 74 x 66 x 616 = 2274459264
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.
36 : 1, 2, 3, 4, 6, 9, 12, 18, 36
21 : 1, 3, 7, 21
74 : 1, 2, 37, 74
66 : 1, 2, 3, 6, 11, 22, 33, 66
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 36,21,74,66,616, is 1.
Now, the common factors can be found like this.
36:2x 2x 3x 3
21:3x 7
74:2x 37
66:2x 3x 11
616:2x 2x 2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 7x 11 = 11088
Therefore, the value for common factors is 11088.
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 = 2274459264/(1x11088)
LCM = 2274459264/11088
LCM = 205128
Thus, we can understand that the LCM of 36,21,74,66,616 is 205128.
