HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 165 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 165 is 11 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 308, 165 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 308, 165 is 11.
HCF(308, 165) = 11
HCF of 308, 165 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 165 is 11.
Highest Common Factor of 308,165 is 11
Step 1: Since 308 > 165, we apply the division lemma to 308 and 165, to get
308 = 165 x 1 + 143
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 143 and 165, to get
165 = 143 x 1 + 22
Step 3: We consider the new divisor 143 and the new remainder 22, and apply the division lemma to get
143 = 22 x 6 + 11
We consider the new divisor 22 and the new remainder 11, and apply the division lemma to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 308 and 165 is 11
Notice that 11 = HCF(22,11) = HCF(143,22) = HCF(165,143) = HCF(308,165) .
