Given numbers are 7,118,142,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,118,142,923 is 762398.
Find LCM of 7,118,142,923 with Prime Factorization
| 2 | 7, 118, 142, 923 |
| 71 | 7, 59, 71, 923 |
| 7, 59, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 7 x 59 x 1 x 13 = 762398
Therefore, the lowest common multiple of 7,118,142,923 is 762398.
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.
7 x 118 x 142 x 923 = 108260516
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.
7 : 1, 7
118 : 1, 2, 59, 118
142 : 1, 2, 71, 142
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,118,142,923, is 1.
Now, the common factors can be found like this.
7:7
118:2x 59
142:2x 71
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71 = 142
Therefore, the value for common factors is 142.
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 = 108260516/(1x142)
LCM = 108260516/142
LCM = 762398
Thus, we can understand that the LCM of 7,118,142,923 is 762398.
