HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 164 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 164 is 4 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 768, 164 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 768, 164 is 4.
HCF(768, 164) = 4
HCF of 768, 164 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 164 is 4.
Highest Common Factor of 768,164 is 4
Step 1: Since 768 > 164, we apply the division lemma to 768 and 164, to get
768 = 164 x 4 + 112
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 112 and 164, to get
164 = 112 x 1 + 52
Step 3: We consider the new divisor 112 and the new remainder 52, and apply the division lemma to get
112 = 52 x 2 + 8
We consider the new divisor 52 and the new remainder 8,and apply the division lemma to get
52 = 8 x 6 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 768 and 164 is 4
Notice that 4 = HCF(8,4) = HCF(52,8) = HCF(112,52) = HCF(164,112) = HCF(768,164) .
