The factors of 35 are: 1, 5, 7, 35 The factors of 49 are: 1, 7, 49
What is the greatest common factor of 91 21 and 49?
The greatest common factor (GCF) of three numbers is the largest number that divides each of the three numbers without leaving a remainder. To find the GCF of 91, 21, and 49, we need to factorize each number. The prime factors of 91 are 7 and 13, the prime factors of 21 are 3 and 7, and the prime factors of 49 are 7 and 7. The common factor among them is 7, so the GCF of 91, 21, and 49 is 7.
Find all factors of 147?
73 is prime, so it is just 1 and 73.
What is the highest common factor of 49 and 21?
The factors of 21 and 1,3,7, and 21Now since 21 is not a factor of 49, but 7 is we can say right away the GCF is 7.
Factors for 49?
49 is known from the times tables to be 72. Thus we can split it into the prime factors 7 and 7. In order to find other factors (other than 1) we multiply these prime factors together. Thus, the factors for 49 are: 1, 7 and 49.
