The factors of 30 are:
1, 2, 3, 5, 6, 10, 15, 30
The factors of 42 are:
1, 2, 3, 6, 7, 14, 21, 42
The GCF has to be 6. There isn't any number on both lists that's greater.

How do you know when you have found the Greatest common factor?
there is no highest common factor
What is the greatest common multiple of 32and 55?
The greatest common multiple of any set of positive numbers is infinity.I suspect you actually want to know the greatest common factor and not multiple.The greatest common factor is 1.
What is the greatest common factor of 315 and 693?
The greatest common factor of 525 and 693 is 21.
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
What is the lowest common factor of 6 and 10?
The GCF is 2.Normally, one wants to know either the least common multiple or the greatest common divisor.The least common multiple of 6 and 10 is 30.The greatest common divisor of 6 and 10 is 2.
How do you know when you have found the Greatest common factor?
there is no highest common factor
What is the greatest common multiple of 32and 55?
The greatest common multiple of any set of positive numbers is infinity.I suspect you actually want to know the greatest common factor and not multiple.The greatest common factor is 1.
How do you know whether to use the greatest common factor or the least common multiple to solve a problem?
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
If the greatest common factor of a and b is 3 what values are possible for the greatest common factor of a squared and b?
a is 3m b is 3n m and n are relatively prime - they do not have any common factors. a2 = 9m2 Since m had no factors in common with n, m2 also has no factors in common with n. We know that 3 is a common factor of a and b. The only new possible factor between a2 and b is the second 3 when a is squared. We do not know whether b had more than one factor of 3. So, the greatest common factor of a2 and b, when the greatest common factor of a and b is 3, is either 3 or 9.
What is the greatest common factor of 55 and 105?
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 55 and 105 is 5
If you know the greatest common factor of two numbers is 1 can you predict what the least common multiple will be?
2
What is the greatest common factor of 315 and 693?
The greatest common factor of 525 and 693 is 21.
What is the greatest common factor of 9681246?
You need at least two numbers to find a GCF. You probably have that here but without spaces between the numbers, we don't know what they are.
What is the greatest common factor of 30 and 54?
The greatest common factor of 30 and 54 is 6.The greatest common factor is the highest number that divides exactly into two or more numbers.30: 1, 2, 3, 5, 6, 10, 15, 3054: 1, 2, 3, 6, 9, 18, 27, 54The greatest common factor of 30 and 54 is is 6.
What is the GMF of 90 and 105?
The greatest common factor (GCF) of 90 and 105 is 15.
Is 11 a greatest common factor?
It sure can be. You never know what the greatest common factor is until you knowthe two numbers that it's a factor of .11 is always the greatest common factor of any two numbers that look like this:=> 11 and (any multiple of 11)=> 22 and (any odd multiple of 11)
what is the largest factor that two numbers share is called?
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
