HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 687 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 843, 687 is 3 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 843, 687 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 843, 687 is 3.
HCF(843, 687) = 3
HCF of 843, 687 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 843, 687 is 3.
Highest Common Factor of 843,687 is 3
Step 1: Since 843 > 687, we apply the division lemma to 843 and 687, to get
843 = 687 x 1 + 156
Step 2: Since the reminder 687 ≠ 0, we apply division lemma to 156 and 687, to get
687 = 156 x 4 + 63
Step 3: We consider the new divisor 156 and the new remainder 63, and apply the division lemma to get
156 = 63 x 2 + 30
We consider the new divisor 63 and the new remainder 30,and apply the division lemma to get
63 = 30 x 2 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 843 and 687 is 3
Notice that 3 = HCF(30,3) = HCF(63,30) = HCF(156,63) = HCF(687,156) = HCF(843,687) .
