Given numbers are 347,638,928,821,998
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,638,928,821,998 is 1451155121504.
Find LCM of 347,638,928,821,998 with Prime Factorization
| 2 | 347, 638, 928, 821, 998 |
| 29 | 347, 319, 464, 821, 499 |
| 347, 11, 16, 821, 499 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 347 x 11 x 16 x 821 x 499 = 1451155121504
Therefore, the lowest common multiple of 347,638,928,821,998 is 1451155121504.
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 638 x 928 x 821 x 998 = 168333994094464
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
638 : 1, 2, 11, 22, 29, 58, 319, 638
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
821 : 1, 821
998 : 1, 2, 499, 998
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,638,928,821,998, is 1.
Now, the common factors can be found like this.
347:347
638:2x 11x 29
928:2x 2x 2x 2x 2x 29
821:821
998:2x 499
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 29 = 116
Therefore, the value for common factors is 116.
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 = 168333994094464/(1x116)
LCM = 168333994094464/116
LCM = 1451155121504
Thus, we can understand that the LCM of 347,638,928,821,998 is 1451155121504.
