Given numbers are 707,647,728,781,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,647,728,781,198 is 334387917864.
Find LCM of 707,647,728,781,198 with Prime Factorization
| 2 | 707, 647, 728, 781, 198 |
| 7 | 707, 647, 364, 781, 99 |
| 11 | 101, 647, 52, 781, 99 |
| 101, 647, 52, 71, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 101 x 647 x 52 x 71 x 9 = 334387917864
Therefore, the lowest common multiple of 707,647,728,781,198 is 334387917864.
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.
707 x 647 x 728 x 781 x 198 = 51495739351056
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.
707 : 1, 7, 101, 707
647 : 1, 647
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
781 : 1, 11, 71, 781
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,647,728,781,198, is 1.
Now, the common factors can be found like this.
707:7x 101
647:647
728:2x 2x 2x 7x 13
781:11x 71
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 51495739351056/(1x154)
LCM = 51495739351056/154
LCM = 334387917864
Thus, we can understand that the LCM of 707,647,728,781,198 is 334387917864.
