15 can be factorized into 3 x 5
42 is factorized as 2 x 3 x 7
Of these factors of these two, greatest common factor is 3.
Where as the LCM is found by multiplying the common factor along with non common ones. ie 3 X 2 X 5 X 7 = 210
So HCF or GCF or GCD (Greatest Common Divisor) is 3
Least common multiple is 210

What are the greatest common factors of 7 42 70?
Greatest common factors of 7 42 & 70 is 7.
What is the greatest common factor of 42 and 86?
The GCF of 42 and 86 is 2. 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 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
What are the common factors and greatest common factor of 21 and 42?
The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.
What are the common factors and greatest common factor of 42?
There is neither a greatest common factor nor common factors of a single number, such as 42, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Examples: The common factors of 25 and 42 are only 1; the greatest common factor is 1. The common factors of 36 and 42 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 42 and 49 are 1 and 7; the greatest common factor is 7. The common factors of 42 and 60 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 42 and 70 are 1, 2, 7, and 14; the greatest common factor is 14.
What is the greatest common factor of 42?
There is not a greatest common factor of 42 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The prime factors of 42 are 2, 3, and 7. Examples: The greatest common factor of 36 and 42 is 6. The greatest common factor of 42 and 91 is 7. The greatest common factor of 42 and 375 is 3.
