Given numbers are 688,770,946,846,887
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,770,946,846,887 is 99383240880.
Find LCM of 688,770,946,846,887 with Prime Factorization
| 2 | 688, 770, 946, 846, 887 |
| 11 | 344, 385, 473, 423, 887 |
| 43 | 344, 35, 43, 423, 887 |
| 8, 35, 1, 423, 887 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 8 x 35 x 1 x 423 x 887 = 99383240880
Therefore, the lowest common multiple of 688,770,946,846,887 is 99383240880.
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.
688 x 770 x 946 x 846 x 887 = 376066183489920
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
946 : 1, 2, 11, 22, 43, 86, 473, 946
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
887 : 1, 887
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,770,946,846,887, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
770:2x 5x 7x 11
946:2x 11x 43
846:2x 3x 3x 47
887:887
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 11x 43 = 3784
Therefore, the value for common factors is 3784.
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 = 376066183489920/(1x3784)
LCM = 376066183489920/3784
LCM = 99383240880
Thus, we can understand that the LCM of 688,770,946,846,887 is 99383240880.
