Given numbers are 724,989,890,466,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,989,890,466,397 is 29474150486020.
Find LCM of 724,989,890,466,397 with Prime Factorization
2 | 724, 989, 890, 466, 397 |
362, 989, 445, 233, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 362 x 989 x 445 x 233 x 397 = 29474150486020
Therefore, the lowest common multiple of 724,989,890,466,397 is 29474150486020.
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.
724 x 989 x 890 x 466 x 397 = 117896601944080
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.
724 : 1, 2, 4, 181, 362, 724
989 : 1, 23, 43, 989
890 : 1, 2, 5, 10, 89, 178, 445, 890
466 : 1, 2, 233, 466
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,989,890,466,397, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
989:23x 43
890:2x 5x 89
466:2x 233
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 117896601944080/(1x4)
LCM = 117896601944080/4
LCM = 29474150486020
Thus, we can understand that the LCM of 724,989,890,466,397 is 29474150486020.
