Given numbers are 770,250,865,165,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,250,865,165,947 is 9461240250.
Find LCM of 770,250,865,165,947 with Prime Factorization
| 2 | 770, 250, 865, 165, 947 |
| 5 | 385, 125, 865, 165, 947 |
| 11 | 77, 25, 173, 33, 947 |
| 7, 25, 173, 3, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 25 x 173 x 3 x 947 = 9461240250
Therefore, the lowest common multiple of 770,250,865,165,947 is 9461240250.
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 250 x 865 x 165 x 947 = 26018410687500
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
250 : 1, 2, 5, 10, 25, 50, 125, 250
865 : 1, 5, 173, 865
165 : 1, 3, 5, 11, 15, 33, 55, 165
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,250,865,165,947, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
250:2x 5x 5x 5
865:5x 173
165:3x 5x 11
947:947
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 5x 5x 11 = 2750
Therefore, the value for common factors is 2750.
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 = 26018410687500/(1x2750)
LCM = 26018410687500/2750
LCM = 9461240250
Thus, we can understand that the LCM of 770,250,865,165,947 is 9461240250.
