Given numbers are 743,946,989,230
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,946,989,230 is 80830970.
Find LCM of 743,946,989,230 with Prime Factorization
| 2 | 743, 946, 989, 230 |
| 23 | 743, 473, 989, 115 |
| 43 | 743, 473, 43, 5 |
| 743, 11, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 43 x 743 x 11 x 1 x 5 = 80830970
Therefore, the lowest common multiple of 743,946,989,230 is 80830970.
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.
743 x 946 x 989 x 230 = 159883658660
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.
743 : 1, 743
946 : 1, 2, 11, 22, 43, 86, 473, 946
989 : 1, 23, 43, 989
230 : 1, 2, 5, 10, 23, 46, 115, 230
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,946,989,230, is 1.
Now, the common factors can be found like this.
743:743
946:2x 11x 43
989:23x 43
230:2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 43 = 1978
Therefore, the value for common factors is 1978.
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 = 159883658660/(1x1978)
LCM = 159883658660/1978
LCM = 80830970
Thus, we can understand that the LCM of 743,946,989,230 is 80830970.
