Given numbers are 142,989,963,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,989,963,989 is 135241794.
Find LCM of 142,989,963,989 with Prime Factorization
23 | 142, 989, 963, 989 |
43 | 142, 43, 963, 43 |
142, 1, 963, 1 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 142 x 1 x 963 x 1 = 135241794
Therefore, the lowest common multiple of 142,989,963,989 is 135241794.
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.
142 x 989 x 963 x 989 = 133754134266
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.
142 : 1, 2, 71, 142
989 : 1, 23, 43, 989
963 : 1, 3, 9, 107, 321, 963
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,989,963,989, is 1.
Now, the common factors can be found like this.
142:2x 71
989:23x 43
963:3x 3x 107
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 43 = 989
Therefore, the value for common factors is 989.
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 = 133754134266/(1x989)
LCM = 133754134266/989
LCM = 135241794
Thus, we can understand that the LCM of 142,989,963,989 is 135241794.
