GCF of 56 and 35 by Long Division
GCF of 56 and 35 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly.
 Step 1: Divide 56 (larger number) by 35 (smaller number).
 Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (35) by the remainder (21).
 Step 3: Repeat this process until the remainder = 0.
The corresponding divisor (7) is the GCF of 56 and 35.
GCF of 56 and 35 by Prime Factorization
Prime factorization of 56 and 35 is (2 × 2 × 2 × 7) and (5 × 7) respectively. As visible, 56 and 35 have only one common prime factor i.e. 7. Hence, the GCF of 56 and 35 is 7.
GCF of 56 and 35 by Euclidean Algorithm
As per the Euclidean Algorithm, GCF(X, Y) = GCF(Y, X mod Y)
where X > Y and mod is the modulo operator.
Here X = 56 and Y = 35
 GCF(56, 35) = GCF(35, 56 mod 35) = GCF(35, 21)
 GCF(35, 21) = GCF(21, 35 mod 21) = GCF(21, 14)
 GCF(21, 14) = GCF(14, 21 mod 14) = GCF(14, 7)
 GCF(14, 7) = GCF(7, 14 mod 7) = GCF(7, 0)
 GCF(7, 0) = 7 (∵ GCF(X, 0) = X, where X ≠ 0)
Therefore, the value of GCF of 56 and 35 is 7.

GCF of 56 and 35 Examples

Example 1: For two numbers, GCF = 7 and LCM = 280. If one number is 35, find the other number.
Solution:
Given: GCF (y, 35) = 7 and LCM (y, 35) = 280
∵ GCF × LCM = 35 × (y)
⇒ y = (GCF × LCM)/35
⇒ y = (7 × 280)/35
⇒ y = 56
Therefore, the other number is 56. 
Example 2: Find the greatest number that divides 56 and 35 exactly.
Solution:
The greatest number that divides 56 and 35 exactly is their greatest common factor, i.e. GCF of 56 and 35.
⇒ Factors of 56 and 35: Factors of 56 = 1, 2, 4, 7, 8, 14, 28, 56
 Factors of 35 = 1, 5, 7, 35

Example 3: The product of two numbers is 1960. If their GCF is 7, what is their LCM?
Solution:
Given: GCF = 7 and product of numbers = 1960
∵ LCM × GCF = product of numbers
⇒ LCM = Product/GCF = 1960/7
Therefore, the LCM is 280.
