Given numbers are 140,112,716,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,112,716,691 is 69265840.
Find LCM of 140,112,716,691 with Prime Factorization
| 2 | 140, 112, 716, 691 |
| 2 | 70, 56, 358, 691 |
| 7 | 35, 28, 179, 691 |
| 5, 4, 179, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 5 x 4 x 179 x 691 = 69265840
Therefore, the lowest common multiple of 140,112,716,691 is 69265840.
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.
140 x 112 x 716 x 691 = 7757774080
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
716 : 1, 2, 4, 179, 358, 716
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,112,716,691, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
112:2x 2x 2x 2x 7
716:2x 2x 179
691:691
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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 7757774080/(1x112)
LCM = 7757774080/112
LCM = 69265840
Thus, we can understand that the LCM of 140,112,716,691 is 69265840.
