Given numbers are 165,760,436,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,760,436,280 is 19136040.
Find LCM of 165,760,436,280 with Prime Factorization
2 | 165, 760, 436, 280 |
2 | 165, 380, 218, 140 |
2 | 165, 190, 109, 70 |
5 | 165, 95, 109, 35 |
33, 19, 109, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 33 x 19 x 109 x 7 = 19136040
Therefore, the lowest common multiple of 165,760,436,280 is 19136040.
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.
165 x 760 x 436 x 280 = 15308832000
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
436 : 1, 2, 4, 109, 218, 436
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,760,436,280, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
760:2x 2x 2x 5x 19
436:2x 2x 109
280:2x 2x 2x 5x 7
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 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 15308832000/(1x800)
LCM = 15308832000/800
LCM = 19136040
Thus, we can understand that the LCM of 165,760,436,280 is 19136040.
