The first step of finding the GCF is to split the numbers into their prime factors. For instance, if I wanted to find the GCF of 30 and 105, I would split these up into: 30 = 2x3x5105 = 3x5x7The next...
The prime factorization of 210 is 2 x 3 x 5 x 7 The prime factorization of 1890 is 2 x 3 x 5 x 7 x 9 The largest number in common out of those two sets is 5. That's the GCF.
A prime number is a number with exactly 2 divisors: 1 and itself. Because of this, the only common divisor of two distinct prime numbers is 1, thus 1 is the gcf. So the correct answer would be: Given...
For example we have 2 Nos. 24 & 36 . GCF =24)36(1 24------------ 12)24(2 24---------------- 0So the last divisor is the GCF of 24 & 36 which is 12 . And the above method is called successive...
