LCM(30, 40, 60) = 120 GCF(30, 40, 60) = 10
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question: 120! The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question: 10!
30 = 3 x 1040 = 4 x 10The GCF of 30 and 40 is 10.30 x 4 = 12040 x 3 = 120The LCM of 30 and 40 is 120.
Two numbers whose greatest common factor (GCF) is 20 are any pair of numbers that are multiples of 20. For example, 20 and 40 have a GCF of 20 because 20 is a factor of both numbers. Another pair could be 60 and 80, as 20 is also a factor of both of these numbers.
There are many possible answers. One possible pair is 2 and 40.
You need at least two numbers to find a GCF.
4 and 40 8 and 20
4 and 40 8 and 20
72 and 40
Let the two numbers be x and y. Let suppose that the average of two numbers is 20. Then,x + y = 40 and 40/GCF = 5, where GCF = 40/5 = 8Since LCM is 48 and GCF is 8, the numbers are 16 and 24, whose average is 20 is true.
4 and 40 8 and 20
40 and 50
40 and 50
You need at least two numbers to find either of those.
The GCF of 5 and 8 is 1. The LCM is 40.
