Given numbers are 391,757,598,743,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,757,598,743,247 is 108639660454.
Find LCM of 391,757,598,743,247 with Prime Factorization
| 13 | 391, 757, 598, 743, 247 |
| 23 | 391, 757, 46, 743, 19 |
| 17, 757, 2, 743, 19 |
Multiply the prime numbers at the bottom and the left side.
13 x 23 x 17 x 757 x 2 x 743 x 19 = 108639660454
Therefore, the lowest common multiple of 391,757,598,743,247 is 108639660454.
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.
391 x 757 x 598 x 743 x 247 = 32483258475746
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.
391 : 1, 17, 23, 391
757 : 1, 757
598 : 1, 2, 13, 23, 26, 46, 299, 598
743 : 1, 743
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,757,598,743,247, is 1.
Now, the common factors can be found like this.
391:17x 23
757:757
598:2x 13x 23
743:743
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 23 = 299
Therefore, the value for common factors is 299.
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 = 32483258475746/(1x299)
LCM = 32483258475746/299
LCM = 108639660454
Thus, we can understand that the LCM of 391,757,598,743,247 is 108639660454.
