There can be no such number.
Suppose x is the least common multiple (LCM) of these numbers. Then 2*LCM is also a common multiple and is greater. And then 3*LCM is a common multiple and greater still. And so on, for ever.
To find the greatest common factor of two numbers, you first need to split these numbers into their prime factors. For 12 and 42 this is:
12 = 2x2x3
42 = 2x3x7
The next step is to identify any common factors. In this case, both numbers have a 2 and a 3 as prime factors. Thus, to find the GCF, you need to multiply those numbers together:
2x3 = 6
So the GCF of 12 and 42 is 6.
The least common factor of any set of positive integers is 1.
The greatest common multiple of any set of integers is infinite.
The GCF is 6.
The least common factor of any set of integers is 1.
The GCF is 6.
The GCF is 6.
GCF of 12 and 42 is 6.
HCF(24, 42) = 6.
6
The GCF is 7.
The Greatest Common Factor (GCF) is: 6
The GCF is 2.
The GCF is 42.
The GCF is 14.
The greatest common factor of 12 and 42 is 6.12 and 42's highest common factor is six.
The greatest common factor of the numbers 12 and 42 is 6.
Highest common factor is 7.
Highest common factor of 36, 42, and 54 is 6.
The GCF is 7.
Yes 6 is the highest common factor of 42 and 48
The greatest common factor of 12 , 42 = 6
18 and 42's highest common factor is six.
The greatest common factor of 42 and 12 is 6.
The highest or greatest common factor of 420 and 294 is 42.
The highest common factor (HCF) is 14.
The highest common factor is 21
