Given numbers are 118,587,405,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 118,587,405,680 is 1907585640.
Find LCM of 118,587,405,680 with Prime Factorization
| 2 | 118, 587, 405, 680 |
| 5 | 59, 587, 405, 340 |
| 59, 587, 81, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 59 x 587 x 81 x 68 = 1907585640
Therefore, the lowest common multiple of 118,587,405,680 is 1907585640.
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 587 x 405 x 680 = 19075856400
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
587 : 1, 587
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,587,405,680, is 1.
Now, the common factors can be found like this.
118:2x 59
587:587
405:3x 3x 3x 3x 5
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 19075856400/(1x10)
LCM = 19075856400/10
LCM = 1907585640
Thus, we can understand that the LCM of 118,587,405,680 is 1907585640.
