HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 26, 689 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 26, 689 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 26, 689 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 26, 689 is 13.
HCF(26, 689) = 13
HCF of 26, 689 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 26, 689 is 13.
Highest Common Factor of 26,689 is 13
Step 1: Since 689 > 26, we apply the division lemma to 689 and 26, to get
689 = 26 x 26 + 13
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 13 and 26, 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 26 and 689 is 13
Notice that 13 = HCF(26,13) = HCF(689,26) .
