HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 156, 6843 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 156, 6843 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 156, 6843 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 156, 6843 is 3.
HCF(156, 6843) = 3
HCF of 156, 6843 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 156, 6843 is 3.
Highest Common Factor of 156,6843 is 3
Step 1: Since 6843 > 156, we apply the division lemma to 6843 and 156, to get
6843 = 156 x 43 + 135
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 135 and 156, to get
156 = 135 x 1 + 21
Step 3: We consider the new divisor 135 and the new remainder 21, and apply the division lemma to get
135 = 21 x 6 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 156 and 6843 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(135,21) = HCF(156,135) = HCF(6843,156) .
