Given numbers are 611,520,685,986,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 611,520,685,986,787 is 1299102505480.
Find LCM of 611,520,685,986,787 with Prime Factorization
| 2 | 611, 520, 685, 986, 787 |
| 5 | 611, 260, 685, 493, 787 |
| 13 | 611, 52, 137, 493, 787 |
| 47, 4, 137, 493, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 47 x 4 x 137 x 493 x 787 = 1299102505480
Therefore, the lowest common multiple of 611,520,685,986,787 is 1299102505480.
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.
611 x 520 x 685 x 986 x 787 = 168883325712400
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.
611 : 1, 13, 47, 611
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
685 : 1, 5, 137, 685
986 : 1, 2, 17, 29, 34, 58, 493, 986
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,520,685,986,787, is 1.
Now, the common factors can be found like this.
611:13x 47
520:2x 2x 2x 5x 13
685:5x 137
986:2x 17x 29
787:787
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 168883325712400/(1x130)
LCM = 168883325712400/130
LCM = 1299102505480
Thus, we can understand that the LCM of 611,520,685,986,787 is 1299102505480.
