The LCM of 661,819,972,182 is 58466772.
Find LCM of 661,819,972,182 with Prime Factorization
| 2 | 661, 819, 972, 182 |
| 3 | 661, 819, 486, 91 |
| 3 | 661, 273, 162, 91 |
| 7 | 661, 91, 54, 91 |
| 13 | 661, 13, 54, 13 |
| 661, 1, 54, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 13 x 661 x 1 x 54 x 1 = 58466772
Therefore, the lowest common multiple of 661,819,972,182 is 58466772.
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.
661 x 819 x 972 x 182 = 95768572536
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.
661 : 1, 661
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
182 : 1, 2, 7, 13, 14, 26, 91, 182
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,819,972,182, is 1.
Now, the common factors can be found like this.
661:661
819:3x 3x 7x 13
972:2x 2x 3x 3x 3x 3x 3
182:2x 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.
2x 3x 3x 7x 13 = 1638
Therefore, the value for common factors is 1638.
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 = 95768572536/(1x1638)
LCM = 95768572536/1638
LCM = 58466772
Thus, we can understand that the LCM of 661,819,972,182 is 58466772.
