HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 73, 22, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 73, 22, 61 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, 73, 22, 61 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, 73, 22, 61 is 1.
HCF(56, 73, 22, 61) = 1
HCF of 56, 73, 22, 61 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, 73, 22, 61 is 1.
Highest Common Factor of 56,73,22,61 is 1
Step 1: Since 73 > 56, we apply the division lemma to 73 and 56, to get
73 = 56 x 1 + 17
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 17 and 56, to get
56 = 17 x 3 + 5
Step 3: We consider the new divisor 17 and the new remainder 5, and apply the division lemma to get
17 = 5 x 3 + 2
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 56 and 73 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(56,17) = HCF(73,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1
Notice that 1 = HCF(22,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1
Notice that 1 = HCF(61,1) .
