HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 168, 816, 482 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 168, 816, 482 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 168, 816, 482 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 168, 816, 482 is 2.
HCF(168, 816, 482) = 2
HCF of 168, 816, 482 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 168, 816, 482 is 2.
Highest Common Factor of 168,816,482 is 2
Step 1: Since 816 > 168, we apply the division lemma to 816 and 168, to get
816 = 168 x 4 + 144
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 144 and 168, to get
168 = 144 x 1 + 24
Step 3: We consider the new divisor 144 and the new remainder 24, and apply the division lemma to get
144 = 24 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 168 and 816 is 24
Notice that 24 = HCF(144,24) = HCF(168,144) = HCF(816,168) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 482 > 24, we apply the division lemma to 482 and 24, to get
482 = 24 x 20 + 2
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 2 and 24, to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 24 and 482 is 2
Notice that 2 = HCF(24,2) = HCF(482,24) .
