To find the greatest common factor (GCF) of 42, 70, and 105, we first need to find the prime factorization of each number.
42 = 2 x 3 x 7 70 = 2 x 5 x 7 105 = 3 x 5 x 7
The GCF is the product of the common prime factors raised to the lowest power they appear in all three numbers. Therefore, the GCF of 42, 70, and 105 is 7.

What is the greatest common factor of 42 105 and 112?
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 42, 105, and 112 is 7
What is the greatest common factor of 42 and 105?
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 105 are 1, 3, 5, 7, 15, 21, 35, and 105.The common factors are 1, 3, 7, and 21. Therefore, the greatest common factor is 21.The GCF of 42 and 105 is 21
Greatest common factor of 24 and 42?
