Given numbers are 987,713,107,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,713,107,517 is 828291387.
Find LCM of 987,713,107,517 with Prime Factorization
47 | 987, 713, 107, 517 |
21, 713, 107, 11 |
Multiply the prime numbers at the bottom and the left side.
47 x 21 x 713 x 107 x 11 = 828291387
Therefore, the lowest common multiple of 987,713,107,517 is 828291387.
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.
987 x 713 x 107 x 517 = 38929695189
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
713 : 1, 23, 31, 713
107 : 1, 107
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,713,107,517, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
713:23x 31
107:107
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
47 = 47
Therefore, the value for common factors is 47.
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 = 38929695189/(1x47)
LCM = 38929695189/47
LCM = 828291387
Thus, we can understand that the LCM of 987,713,107,517 is 828291387.
