The factors of 35 are: 1, 5, 7, 35 The factors of 49 are: 1, 7, 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.
73 is prime, so it is just 1 and 73.
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.
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.
The factors of 21 are 1, 3, 7, and 21. The factors of 49 are 1, 7, and 49.
Factors or 21 are: 1 3 7 21 Factors or 49 are: 1 7 49 Common factors of 21 and 49 are: 1 and 7
Factors of 21 are 3 and 7 (21=3x7). Factors of 35 are 5 and 7 (35=5x7). Factors of 49 are 7 and 7 (49=7x7).
The factors of 21 are 1, 3, 7, 21 The factors of 49 are 1, 7, 49 The largest matching number is 7 so 7 is the GCF of 21 and 49.
the factors of 21 are 3,7,1, 21,and -1, -21,-3,-7. the factors of 49 are 1,49,7,7 and -1, -21-7-7.
The factors of 21 are:1, 3, 7, 21The factors of 49 are:1, 7, 49The common factors are:1, 7
To find the greatest common factor of 21, 42, and 49, we first need to find the prime factors of each number. The prime factors of 21 are 3 and 7, the prime factors of 42 are 2, 3, and 7, and the prime factors of 49 are 7 and 7. The greatest common factor is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 7. Therefore, the greatest common factor of 21, 42, and 49 is 7.
