Given numbers are 723,974,491,982
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,974,491,982 is 345763182.
Find LCM of 723,974,491,982 with Prime Factorization
| 2 | 723, 974, 491, 982 |
| 491 | 723, 487, 491, 491 |
| 723, 487, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 491 x 723 x 487 x 1 x 1 = 345763182
Therefore, the lowest common multiple of 723,974,491,982 is 345763182.
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.
723 x 974 x 491 x 982 = 339539444724
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.
723 : 1, 3, 241, 723
974 : 1, 2, 487, 974
491 : 1, 491
982 : 1, 2, 491, 982
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,974,491,982, is 1.
Now, the common factors can be found like this.
723:3x 241
974:2x 487
491:491
982:2x 491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 491 = 982
Therefore, the value for common factors is 982.
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 = 339539444724/(1x982)
LCM = 339539444724/982
LCM = 345763182
Thus, we can understand that the LCM of 723,974,491,982 is 345763182.
