HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 838 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 672, 838 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 672, 838 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 672, 838 is 2.
HCF(672, 838) = 2
HCF of 672, 838 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 672, 838 is 2.
Highest Common Factor of 672,838 is 2
Step 1: Since 838 > 672, we apply the division lemma to 838 and 672, to get
838 = 672 x 1 + 166
Step 2: Since the reminder 672 ≠ 0, we apply division lemma to 166 and 672, to get
672 = 166 x 4 + 8
Step 3: We consider the new divisor 166 and the new remainder 8, and apply the division lemma to get
166 = 8 x 20 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 672 and 838 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(166,8) = HCF(672,166) = HCF(838,672) .
