HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 308 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 308 is 4 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 816, 308 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 816, 308 is 4.
HCF(816, 308) = 4
HCF of 816, 308 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 308 is 4.
Highest Common Factor of 816,308 is 4
Step 1: Since 816 > 308, we apply the division lemma to 816 and 308, to get
816 = 308 x 2 + 200
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 200 and 308, to get
308 = 200 x 1 + 108
Step 3: We consider the new divisor 200 and the new remainder 108, and apply the division lemma to get
200 = 108 x 1 + 92
We consider the new divisor 108 and the new remainder 92,and apply the division lemma to get
108 = 92 x 1 + 16
We consider the new divisor 92 and the new remainder 16,and apply the division lemma to get
92 = 16 x 5 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 816 and 308 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(92,16) = HCF(108,92) = HCF(200,108) = HCF(308,200) = HCF(816,308) .
