Given numbers are 770,641,861,910,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,641,861,910,162 is 21308897610.
Find LCM of 770,641,861,910,162 with Prime Factorization
| 2 | 770, 641, 861, 910, 162 |
| 3 | 385, 641, 861, 455, 81 |
| 5 | 385, 641, 287, 455, 27 |
| 7 | 77, 641, 287, 91, 27 |
| 11, 641, 41, 13, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 641 x 41 x 13 x 27 = 21308897610
Therefore, the lowest common multiple of 770,641,861,910,162 is 21308897610.
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.
770 x 641 x 861 x 910 x 162 = 62648158973400
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
641 : 1, 641
861 : 1, 3, 7, 21, 41, 123, 287, 861
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,641,861,910,162, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
641:641
861:3x 7x 41
910:2x 5x 7x 13
162:2x 3x 3x 3x 3
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 3x 5x 7x 7 = 2940
Therefore, the value for common factors is 2940.
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 = 62648158973400/(1x2940)
LCM = 62648158973400/2940
LCM = 21308897610
Thus, we can understand that the LCM of 770,641,861,910,162 is 21308897610.
