Given numbers are 981,750,892,392,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,750,892,392,769 is 8243208603000.
Find LCM of 981,750,892,392,769 with Prime Factorization
| 2 | 981, 750, 892, 392, 769 |
| 2 | 981, 375, 446, 196, 769 |
| 3 | 981, 375, 223, 98, 769 |
| 327, 125, 223, 98, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 327 x 125 x 223 x 98 x 769 = 8243208603000
Therefore, the lowest common multiple of 981,750,892,392,769 is 8243208603000.
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.
981 x 750 x 892 x 392 x 769 = 197837006472000
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.
981 : 1, 3, 9, 109, 327, 981
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
892 : 1, 2, 4, 223, 446, 892
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,750,892,392,769, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
750:2x 3x 5x 5x 5
892:2x 2x 223
392:2x 2x 2x 7x 7
769:769
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 197837006472000/(1x24)
LCM = 197837006472000/24
LCM = 8243208603000
Thus, we can understand that the LCM of 981,750,892,392,769 is 8243208603000.
