HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 935, 646 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 935, 646 is 17 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 935, 646 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 935, 646 is 17.
HCF(935, 646) = 17
HCF of 935, 646 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 935, 646 is 17.
Highest Common Factor of 935,646 is 17
Step 1: Since 935 > 646, we apply the division lemma to 935 and 646, to get
935 = 646 x 1 + 289
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 289 and 646, to get
646 = 289 x 2 + 68
Step 3: We consider the new divisor 289 and the new remainder 68, and apply the division lemma to get
289 = 68 x 4 + 17
We consider the new divisor 68 and the new remainder 17, and apply the division lemma to get
68 = 17 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 935 and 646 is 17
Notice that 17 = HCF(68,17) = HCF(289,68) = HCF(646,289) = HCF(935,646) .
