Given numbers are 402,921,988,386,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 402,921,988,386,968 is 2847502096296.
Find LCM of 402,921,988,386,968 with Prime Factorization
2 | 402, 921, 988, 386, 968 |
2 | 201, 921, 494, 193, 484 |
3 | 201, 921, 247, 193, 242 |
67, 307, 247, 193, 242 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 67 x 307 x 247 x 193 x 242 = 2847502096296
Therefore, the lowest common multiple of 402,921,988,386,968 is 2847502096296.
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.
402 x 921 x 988 x 386 x 968 = 136680100622208
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.
402 : 1, 2, 3, 6, 67, 134, 201, 402
921 : 1, 3, 307, 921
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
386 : 1, 2, 193, 386
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,921,988,386,968, is 1.
Now, the common factors can be found like this.
402:2x 3x 67
921:3x 307
988:2x 2x 13x 19
386:2x 193
968:2x 2x 2x 11x 11
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 136680100622208/(1x48)
LCM = 136680100622208/48
LCM = 2847502096296
Thus, we can understand that the LCM of 402,921,988,386,968 is 2847502096296.
