Given numbers are 905,973,588,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,973,588,255 is 1257446820.
Find LCM of 905,973,588,255 with Prime Factorization
| 3 | 905, 973, 588, 255 |
| 5 | 905, 973, 196, 85 |
| 7 | 181, 973, 196, 17 |
| 181, 139, 28, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 181 x 139 x 28 x 17 = 1257446820
Therefore, the lowest common multiple of 905,973,588,255 is 1257446820.
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.
905 x 973 x 588 x 255 = 132031916100
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.
905 : 1, 5, 181, 905
973 : 1, 7, 139, 973
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,973,588,255, is 1.
Now, the common factors can be found like this.
905:5x 181
973:7x 139
588:2x 2x 3x 7x 7
255:3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 132031916100/(1x105)
LCM = 132031916100/105
LCM = 1257446820
Thus, we can understand that the LCM of 905,973,588,255 is 1257446820.
