Given numbers are 770,561,865,606,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,561,865,606,165 is 686164710.
Find LCM of 770,561,865,606,165 with Prime Factorization
| 2 | 770, 561, 865, 606, 165 |
| 3 | 385, 561, 865, 303, 165 |
| 5 | 385, 187, 865, 101, 55 |
| 11 | 77, 187, 173, 101, 11 |
| 7, 17, 173, 101, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 7 x 17 x 173 x 101 x 1 = 686164710
Therefore, the lowest common multiple of 770,561,865,606,165 is 686164710.
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 561 x 865 x 606 x 165 = 37361668459500
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
865 : 1, 5, 173, 865
606 : 1, 2, 3, 6, 101, 202, 303, 606
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,561,865,606,165, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
561:3x 11x 17
865:5x 173
606:2x 3x 101
165:3x 5x 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 3x 3x 5x 5x 11x 11 = 54450
Therefore, the value for common factors is 54450.
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 = 37361668459500/(1x54450)
LCM = 37361668459500/54450
LCM = 686164710
Thus, we can understand that the LCM of 770,561,865,606,165 is 686164710.
