Given numbers are 974,747,961,395,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,747,961,395,645 is 11875953749130.
Find LCM of 974,747,961,395,645 with Prime Factorization
3 | 974, 747, 961, 395, 645 |
5 | 974, 249, 961, 395, 215 |
974, 249, 961, 79, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 974 x 249 x 961 x 79 x 43 = 11875953749130
Therefore, the lowest common multiple of 974,747,961,395,645 is 11875953749130.
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.
974 x 747 x 961 x 395 x 645 = 178139306236950
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.
974 : 1, 2, 487, 974
747 : 1, 3, 9, 83, 249, 747
961 : 1, 31, 961
395 : 1, 5, 79, 395
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,747,961,395,645, is 1.
Now, the common factors can be found like this.
974:2x 487
747:3x 3x 83
961:31x 31
395:5x 79
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 178139306236950/(1x15)
LCM = 178139306236950/15
LCM = 11875953749130
Thus, we can understand that the LCM of 974,747,961,395,645 is 11875953749130.
