The LCM of 972,555,198,946 is 85054860.
Find LCM of 972,555,198,946 with Prime Factorization
| 2 | 972, 555, 198, 946 |
| 3 | 486, 555, 99, 473 |
| 3 | 162, 185, 33, 473 |
| 11 | 54, 185, 11, 473 |
| 54, 185, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 54 x 185 x 1 x 43 = 85054860
Therefore, the lowest common multiple of 972,555,198,946 is 85054860.
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.
972 x 555 x 198 x 946 = 101045173680
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
555 : 1, 3, 5, 15, 37, 111, 185, 555
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,555,198,946, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
555:3x 5x 37
198:2x 3x 3x 11
946:2x 11x 43
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 3x 3x 3x 11 = 1188
Therefore, the value for common factors is 1188.
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 = 101045173680/(1x1188)
LCM = 101045173680/1188
LCM = 85054860
Thus, we can understand that the LCM of 972,555,198,946 is 85054860.
