HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 80, 44, 69 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 80, 44, 69 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, 80, 44, 69 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, 80, 44, 69 is 1.
HCF(56, 80, 44, 69) = 1
HCF of 56, 80, 44, 69 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, 80, 44, 69 is 1.
Highest Common Factor of 56,80,44,69 is 1
Step 1: Since 80 > 56, we apply the division lemma to 80 and 56, to get
80 = 56 x 1 + 24
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 24 and 56, to get
56 = 24 x 2 + 8
Step 3: We consider the new divisor 24 and the new remainder 8, and apply the division lemma to get
24 = 8 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 56 and 80 is 8
Notice that 8 = HCF(24,8) = HCF(56,24) = HCF(80,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 44 > 8, we apply the division lemma to 44 and 8, to get
44 = 8 x 5 + 4
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 4 and 8, to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 8 and 44 is 4
Notice that 4 = HCF(8,4) = HCF(44,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 4, we apply the division lemma to 69 and 4, to get
69 = 4 x 17 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 69 is 1
Notice that 1 = HCF(4,1) = HCF(69,4) .
