Given numbers are 347,391,171,978,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,391,171,978,901 is 400862852226.
Find LCM of 347,391,171,978,901 with Prime Factorization
| 3 | 347, 391, 171, 978, 901 |
| 17 | 347, 391, 57, 326, 901 |
| 347, 23, 57, 326, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 347 x 23 x 57 x 326 x 53 = 400862852226
Therefore, the lowest common multiple of 347,391,171,978,901 is 400862852226.
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.
347 x 391 x 171 x 978 x 901 = 20444005463526
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.
347 : 1, 347
391 : 1, 17, 23, 391
171 : 1, 3, 9, 19, 57, 171
978 : 1, 2, 3, 6, 163, 326, 489, 978
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,391,171,978,901, is 1.
Now, the common factors can be found like this.
347:347
391:17x 23
171:3x 3x 19
978:2x 3x 163
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 20444005463526/(1x51)
LCM = 20444005463526/51
LCM = 400862852226
Thus, we can understand that the LCM of 347,391,171,978,901 is 400862852226.
