Given numbers are 976,770,557,645,497
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 976,770,557,645,497 is 1916963312880.
Find LCM of 976,770,557,645,497 with Prime Factorization
| 2 | 976, 770, 557, 645, 497 |
| 5 | 488, 385, 557, 645, 497 |
| 7 | 488, 77, 557, 129, 497 |
| 488, 11, 557, 129, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 488 x 11 x 557 x 129 x 71 = 1916963312880
Therefore, the lowest common multiple of 976,770,557,645,497 is 1916963312880.
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.
976 x 770 x 557 x 645 x 497 = 134187431901600
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
557 : 1, 557
645 : 1, 3, 5, 15, 43, 129, 215, 645
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,770,557,645,497, is 1.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
770:2x 5x 7x 11
557:557
645:3x 5x 43
497:7x 71
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 7 = 70
Therefore, the value for common factors is 70.
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 = 134187431901600/(1x70)
LCM = 134187431901600/70
LCM = 1916963312880
Thus, we can understand that the LCM of 976,770,557,645,497 is 1916963312880.
