Given numbers are 386,782,651,834,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,782,651,834,392 is 382399998792.
Find LCM of 386,782,651,834,392 with Prime Factorization
| 2 | 386, 782, 651, 834, 392 |
| 3 | 193, 391, 651, 417, 196 |
| 7 | 193, 391, 217, 139, 196 |
| 193, 391, 31, 139, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 193 x 391 x 31 x 139 x 28 = 382399998792
Therefore, the lowest common multiple of 386,782,651,834,392 is 382399998792.
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.
386 x 782 x 651 x 834 x 392 = 64243199797056
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.
386 : 1, 2, 193, 386
782 : 1, 2, 17, 23, 34, 46, 391, 782
651 : 1, 3, 7, 21, 31, 93, 217, 651
834 : 1, 2, 3, 6, 139, 278, 417, 834
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,782,651,834,392, is 1.
Now, the common factors can be found like this.
386:2x 193
782:2x 17x 23
651:3x 7x 31
834:2x 3x 139
392:2x 2x 2x 7x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 64243199797056/(1x168)
LCM = 64243199797056/168
LCM = 382399998792
Thus, we can understand that the LCM of 386,782,651,834,392 is 382399998792.
