Given numbers are 975,365,830,670,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,365,830,670,981 is 258855930450.
Find LCM of 975,365,830,670,981 with Prime Factorization
| 2 | 975, 365, 830, 670, 981 |
| 3 | 975, 365, 415, 335, 981 |
| 5 | 325, 365, 415, 335, 327 |
| 65, 73, 83, 67, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 65 x 73 x 83 x 67 x 327 = 258855930450
Therefore, the lowest common multiple of 975,365,830,670,981 is 258855930450.
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.
975 x 365 x 830 x 670 x 981 = 194141947837500
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
365 : 1, 5, 73, 365
830 : 1, 2, 5, 10, 83, 166, 415, 830
670 : 1, 2, 5, 10, 67, 134, 335, 670
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,365,830,670,981, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
365:5x 73
830:2x 5x 83
670:2x 5x 67
981:3x 3x 109
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 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 194141947837500/(1x750)
LCM = 194141947837500/750
LCM = 258855930450
Thus, we can understand that the LCM of 975,365,830,670,981 is 258855930450.
