Given numbers are 397,953,924,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,953,924,981 is 114314976468.
Find LCM of 397,953,924,981 with Prime Factorization
| 3 | 397, 953, 924, 981 |
| 397, 953, 308, 327 |
Multiply the prime numbers at the bottom and the left side.
3 x 397 x 953 x 308 x 327 = 114314976468
Therefore, the lowest common multiple of 397,953,924,981 is 114314976468.
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.
397 x 953 x 924 x 981 = 342944929404
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.
397 : 1, 397
953 : 1, 953
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
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 397,953,924,981, is 1.
Now, the common factors can be found like this.
397:397
953:953
924:2x 2x 3x 7x 11
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.
3 = 3
Therefore, the value for common factors is 3.
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 = 342944929404/(1x3)
LCM = 342944929404/3
LCM = 114314976468
Thus, we can understand that the LCM of 397,953,924,981 is 114314976468.
