Given numbers are 923,142,107,994,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,142,107,994,657 is 908403678.
Find LCM of 923,142,107,994,657 with Prime Factorization
| 2 | 923, 142, 107, 994, 657 |
| 71 | 923, 71, 107, 497, 657 |
| 13, 1, 107, 7, 657 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 13 x 1 x 107 x 7 x 657 = 908403678
Therefore, the lowest common multiple of 923,142,107,994,657 is 908403678.
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.
923 x 142 x 107 x 994 x 657 = 9158525881596
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.
923 : 1, 13, 71, 923
142 : 1, 2, 71, 142
107 : 1, 107
994 : 1, 2, 7, 14, 71, 142, 497, 994
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,142,107,994,657, is 1.
Now, the common factors can be found like this.
923:13x 71
142:2x 71
107:107
994:2x 7x 71
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71x 71 = 10082
Therefore, the value for common factors is 10082.
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 = 9158525881596/(1x10082)
LCM = 9158525881596/10082
LCM = 908403678
Thus, we can understand that the LCM of 923,142,107,994,657 is 908403678.
