Answer:
7 is the answer
Step-by-step explanation:
Methods to find GCF of 72 and 90
Listing the common factors Method
Long division Method
Method 1: GCF of 21 and 49 by Listing the Common Factors
Factors of 21: 1, 3, 7, and 21
Factors of 49: 1, 7, and 49
Common Factors of 21 and 49: 1 and 7
Greatest Common Factor of 21 and 49 from the list = 7
GCF of 21 and 49 is 7
Method 2: GCF of 21 and 49 by Long Division Method
Step 1: Divide 49 by 21 and check the remainder.
Step 2: Make the remainder of the above step as the divisor and the divisor of the above step as the dividend and perform the long division again.
Step 3: Continue till you get the remainder as 0
The GCF of 21 and 49 will be the last divisor in the division process.
So, the last divisor is 7
Clearly, in both the methods, the GCF of 21 and 49 is the same.
Therefore, GCF of 21 and 49 is 7
