It is: 21
HCF(63, 35) = 7
Since numbers can go on forever there is no "largest number".
The concept of the GCF refers to integers, not decimals.
1 because 7 is a prime number
Two number are co-prime if there is no whole number other than 1 that divides them both exactly
1 The factors of 7 are 1 and 7 (7 is prime) The factors of 12 are 1, 2, 3, 4, 6, and 12 The only factor they share is 1
Just 1.
Yes.1 divides 2 exactly, and it divides 4 exactly, so it is a common factor of them both (as also is 2).
numbers are infinite so this question is impossible, but 30,60,90,120, and so forth go into 30 and 10 evenly.
21. 63 = 32 x 7 84 = 22 x 3 x 7 hcf = 3 x 7 = 21
