Given numbers are 308,770,550,889,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,770,550,889,686 is 47917100.
Find LCM of 308,770,550,889,686 with Prime Factorization
| 2 | 308, 770, 550, 889, 686 |
| 5 | 154, 385, 275, 889, 343 |
| 7 | 154, 77, 55, 889, 343 |
| 11 | 22, 11, 55, 127, 49 |
| 2, 1, 5, 127, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 2 x 1 x 5 x 127 x 49 = 47917100
Therefore, the lowest common multiple of 308,770,550,889,686 is 47917100.
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.
308 x 770 x 550 x 889 x 686 = 79548136052000
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
889 : 1, 7, 127, 889
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,770,550,889,686, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
770:2x 5x 7x 11
550:2x 5x 5x 11
889:7x 127
686:2x 7x 7x 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 5x 7x 7x 7x 11x 11 = 1660120
Therefore, the value for common factors is 1660120.
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 = 79548136052000/(1x1660120)
LCM = 79548136052000/1660120
LCM = 47917100
Thus, we can understand that the LCM of 308,770,550,889,686 is 47917100.
