HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 611 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 611 is 13 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 728, 611 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 728, 611 is 13.
HCF(728, 611) = 13
HCF of 728, 611 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 728, 611 is 13.
Highest Common Factor of 728,611 is 13
Step 1: Since 728 > 611, we apply the division lemma to 728 and 611, to get
728 = 611 x 1 + 117
Step 2: Since the reminder 611 ≠ 0, we apply division lemma to 117 and 611, to get
611 = 117 x 5 + 26
Step 3: We consider the new divisor 117 and the new remainder 26, and apply the division lemma to get
117 = 26 x 4 + 13
We consider the new divisor 26 and the new remainder 13, and apply the division lemma to get
26 = 13 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 728 and 611 is 13
Notice that 13 = HCF(26,13) = HCF(117,26) = HCF(611,117) = HCF(728,611) .
