Given numbers are 347,817,649,903,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,817,649,903,912 is 61820925936.
Find LCM of 347,817,649,903,912 with Prime Factorization
| 3 | 347, 817, 649, 903, 912 |
| 19 | 347, 817, 649, 301, 304 |
| 43 | 347, 43, 649, 301, 16 |
| 347, 1, 649, 7, 16 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 43 x 347 x 1 x 649 x 7 x 16 = 61820925936
Therefore, the lowest common multiple of 347,817,649,903,912 is 61820925936.
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 817 x 649 x 903 x 912 = 151523089469136
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
817 : 1, 19, 43, 817
649 : 1, 11, 59, 649
903 : 1, 3, 7, 21, 43, 129, 301, 903
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,817,649,903,912, is 1.
Now, the common factors can be found like this.
347:347
817:19x 43
649:11x 59
903:3x 7x 43
912:2x 2x 2x 2x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 43 = 2451
Therefore, the value for common factors is 2451.
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 = 151523089469136/(1x2451)
LCM = 151523089469136/2451
LCM = 61820925936
Thus, we can understand that the LCM of 347,817,649,903,912 is 61820925936.
