HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 429 i.e. 33 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 429 is 33 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 165, 429 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 165, 429 is 33.
HCF(165, 429) = 33
HCF of 165, 429 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 429 is 33.
Highest Common Factor of 165,429 is 33
Step 1: Since 429 > 165, we apply the division lemma to 429 and 165, to get
429 = 165 x 2 + 99
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 99 and 165, to get
165 = 99 x 1 + 66
Step 3: We consider the new divisor 99 and the new remainder 66, and apply the division lemma to get
99 = 66 x 1 + 33
We consider the new divisor 66 and the new remainder 33, and apply the division lemma to get
66 = 33 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 165 and 429 is 33
Notice that 33 = HCF(66,33) = HCF(99,66) = HCF(165,99) = HCF(429,165) .
