Given numbers are 865,770,371,171,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,770,371,171,665 is 1207282230.
Find LCM of 865,770,371,171,665 with Prime Factorization
5 | 865, 770, 371, 171, 665 |
7 | 173, 154, 371, 171, 133 |
19 | 173, 22, 53, 171, 19 |
173, 22, 53, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 19 x 173 x 22 x 53 x 9 x 1 = 1207282230
Therefore, the lowest common multiple of 865,770,371,171,665 is 1207282230.
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.
865 x 770 x 371 x 171 x 665 = 28099493903250
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.
865 : 1, 5, 173, 865
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
371 : 1, 7, 53, 371
171 : 1, 3, 9, 19, 57, 171
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,770,371,171,665, is 1.
Now, the common factors can be found like this.
865:5x 173
770:2x 5x 7x 11
371:7x 53
171:3x 3x 19
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 7x 19 = 23275
Therefore, the value for common factors is 23275.
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 = 28099493903250/(1x23275)
LCM = 28099493903250/23275
LCM = 1207282230
Thus, we can understand that the LCM of 865,770,371,171,665 is 1207282230.
