HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 836 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 663, 836 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 663, 836 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 663, 836 is 1.
HCF(663, 836) = 1
HCF of 663, 836 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 663, 836 is 1.
Highest Common Factor of 663,836 is 1
Step 1: Since 836 > 663, we apply the division lemma to 836 and 663, to get
836 = 663 x 1 + 173
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 173 and 663, to get
663 = 173 x 3 + 144
Step 3: We consider the new divisor 173 and the new remainder 144, and apply the division lemma to get
173 = 144 x 1 + 29
We consider the new divisor 144 and the new remainder 29,and apply the division lemma to get
144 = 29 x 4 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 663 and 836 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(144,29) = HCF(173,144) = HCF(663,173) = HCF(836,663) .
