Given numbers are 118,810,685,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 118,810,685,654 is 713648070.
Find LCM of 118,810,685,654 with Prime Factorization
| 2 | 118, 810, 685, 654 |
| 3 | 59, 405, 685, 327 |
| 5 | 59, 135, 685, 109 |
| 59, 27, 137, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 59 x 27 x 137 x 109 = 713648070
Therefore, the lowest common multiple of 118,810,685,654 is 713648070.
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.
118 x 810 x 685 x 654 = 42818884200
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.
118 : 1, 2, 59, 118
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
685 : 1, 5, 137, 685
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,810,685,654, is 1.
Now, the common factors can be found like this.
118:2x 59
810:2x 3x 3x 3x 3x 5
685:5x 137
654:2x 3x 109
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 5 = 60
Therefore, the value for common factors is 60.
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 = 42818884200/(1x60)
LCM = 42818884200/60
LCM = 713648070
Thus, we can understand that the LCM of 118,810,685,654 is 713648070.
