Given numbers are 248,981,713,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,981,713,972 is 151081848.
Find LCM of 248,981,713,972 with Prime Factorization
| 2 | 248, 981, 713, 972 |
| 2 | 124, 981, 713, 486 |
| 3 | 62, 981, 713, 243 |
| 3 | 62, 327, 713, 81 |
| 31 | 62, 109, 713, 27 |
| 2, 109, 23, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 31 x 2 x 109 x 23 x 27 = 151081848
Therefore, the lowest common multiple of 248,981,713,972 is 151081848.
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.
248 x 981 x 713 x 972 = 168607342368
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
981 : 1, 3, 9, 109, 327, 981
713 : 1, 23, 31, 713
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,981,713,972, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
981:3x 3x 109
713:23x 31
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 31 = 1116
Therefore, the value for common factors is 1116.
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 = 168607342368/(1x1116)
LCM = 168607342368/1116
LCM = 151081848
Thus, we can understand that the LCM of 248,981,713,972 is 151081848.
