Given numbers are 998,989,688,942,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,989,688,942,441 is 546707537712.
Find LCM of 998,989,688,942,441 with Prime Factorization
| 2 | 998, 989, 688, 942, 441 |
| 3 | 499, 989, 344, 471, 441 |
| 43 | 499, 989, 344, 157, 147 |
| 499, 23, 8, 157, 147 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 499 x 23 x 8 x 157 x 147 = 546707537712
Therefore, the lowest common multiple of 998,989,688,942,441 is 546707537712.
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.
998 x 989 x 688 x 942 x 441 = 282101089459392
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.
998 : 1, 2, 499, 998
989 : 1, 23, 43, 989
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
942 : 1, 2, 3, 6, 157, 314, 471, 942
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,989,688,942,441, is 1.
Now, the common factors can be found like this.
998:2x 499
989:23x 43
688:2x 2x 2x 2x 43
942:2x 3x 157
441:3x 3x 7x 7
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 3x 43 = 516
Therefore, the value for common factors is 516.
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 = 282101089459392/(1x516)
LCM = 282101089459392/516
LCM = 546707537712
Thus, we can understand that the LCM of 998,989,688,942,441 is 546707537712.
