HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 22, 54, 168, 182 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 22, 54, 168, 182 is 2 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 22, 54, 168, 182 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 22, 54, 168, 182 is 2.
HCF(22, 54, 168, 182) = 2
HCF of 22, 54, 168, 182 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 22, 54, 168, 182 is 2.
Highest Common Factor of 22,54,168,182 is 2
Step 1: Since 54 > 22, we apply the division lemma to 54 and 22, to get
54 = 22 x 2 + 10
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 10 and 22, to get
22 = 10 x 2 + 2
Step 3: We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 22 and 54 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(54,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 168 > 2, we apply the division lemma to 168 and 2, to get
168 = 2 x 84 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 168 is 2
Notice that 2 = HCF(168,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 182 > 2, we apply the division lemma to 182 and 2, to get
182 = 2 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 182 is 2
Notice that 2 = HCF(182,2) .
