Given numbers are 755,170,931,353,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,170,931,353,819 is 987043099770.
Find LCM of 755,170,931,353,819 with Prime Factorization
| 5 | 755, 170, 931, 353, 819 |
| 7 | 151, 34, 931, 353, 819 |
| 151, 34, 133, 353, 117 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 151 x 34 x 133 x 353 x 117 = 987043099770
Therefore, the lowest common multiple of 755,170,931,353,819 is 987043099770.
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.
755 x 170 x 931 x 353 x 819 = 34546508491950
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.
755 : 1, 5, 151, 755
170 : 1, 2, 5, 10, 17, 34, 85, 170
931 : 1, 7, 19, 49, 133, 931
353 : 1, 353
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,170,931,353,819, is 1.
Now, the common factors can be found like this.
755:5x 151
170:2x 5x 17
931:7x 7x 19
353:353
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 34546508491950/(1x35)
LCM = 34546508491950/35
LCM = 987043099770
Thus, we can understand that the LCM of 755,170,931,353,819 is 987043099770.
