HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 238 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 856, 238 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 856, 238 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 856, 238 is 2.
HCF(856, 238) = 2
HCF of 856, 238 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 856, 238 is 2.
Highest Common Factor of 856,238 is 2
Step 1: Since 856 > 238, we apply the division lemma to 856 and 238, to get
856 = 238 x 3 + 142
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 142 and 238, to get
238 = 142 x 1 + 96
Step 3: We consider the new divisor 142 and the new remainder 96, and apply the division lemma to get
142 = 96 x 1 + 46
We consider the new divisor 96 and the new remainder 46,and apply the division lemma to get
96 = 46 x 2 + 4
We consider the new divisor 46 and the new remainder 4,and apply the division lemma to get
46 = 4 x 11 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 856 and 238 is 2
Notice that 2 = HCF(4,2) = HCF(46,4) = HCF(96,46) = HCF(142,96) = HCF(238,142) = HCF(856,238) .
