Given numbers are 997,989,979,478,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 997,989,979,478,144 is 33222670181712.
Find LCM of 997,989,979,478,144 with Prime Factorization
2 | 997, 989, 979, 478, 144 |
997, 989, 979, 239, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 997 x 989 x 979 x 239 x 72 = 33222670181712
Therefore, the lowest common multiple of 997,989,979,478,144 is 33222670181712.
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.
997 x 989 x 979 x 478 x 144 = 66445340363424
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.
997 : 1, 997
989 : 1, 23, 43, 989
979 : 1, 11, 89, 979
478 : 1, 2, 239, 478
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,989,979,478,144, is 1.
Now, the common factors can be found like this.
997:997
989:23x 43
979:11x 89
478:2x 239
144:2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 66445340363424/(1x2)
LCM = 66445340363424/2
LCM = 33222670181712
Thus, we can understand that the LCM of 997,989,979,478,144 is 33222670181712.
