Find LCM of 980,774,308,546,171 with Prime Factorization
| 2 | 980, 774, 308, 546, 171 |
| 2 | 490, 387, 154, 273, 171 |
| 3 | 245, 387, 77, 273, 171 |
| 3 | 245, 129, 77, 91, 57 |
| 7 | 245, 43, 77, 91, 19 |
| 35, 43, 11, 13, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 35 x 43 x 11 x 13 x 19 = 1030449420
Therefore, the lowest common multiple of 980,774,308,546,171 is 1030449420.
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.
980 x 774 x 308 x 546 x 171 = 21812553322560
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,774,308,546,171, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
774:2x 3x 3x 43
308:2x 2x 7x 11
546:2x 3x 7x 13
171:3x 3x 19
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 3x 7x 7 = 21168
Therefore, the value for common factors is 21168.
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 = 21812553322560/(1x21168)
LCM = 21812553322560/21168
LCM = 1030449420
Thus, we can understand that the LCM of 980,774,308,546,171 is 1030449420.
