HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 77, 12, 196 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 77, 12, 196 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 56, 77, 12, 196 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 56, 77, 12, 196 is 1.
HCF(56, 77, 12, 196) = 1
HCF of 56, 77, 12, 196 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 56, 77, 12, 196 is 1.
Highest Common Factor of 56,77,12,196 is 1
Step 1: Since 77 > 56, we apply the division lemma to 77 and 56, to get
77 = 56 x 1 + 21
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 21 and 56, to get
56 = 21 x 2 + 14
Step 3: We consider the new divisor 21 and the new remainder 14, and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7, and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 56 and 77 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(56,21) = HCF(77,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 7, we apply the division lemma to 12 and 7, to get
12 = 7 x 1 + 5
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 5 and 7, to get
7 = 5 x 1 + 2
Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 12 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 196 > 1, we apply the division lemma to 196 and 1, to get
196 = 1 x 196 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 196 is 1
Notice that 1 = HCF(196,1) .
