HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 891 i.e. 81 the largest integer that leaves a remainder zero for all numbers.
HCF of 81, 891 is 81 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 81, 891 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 81, 891 is 81.
HCF(81, 891) = 81
HCF of 81, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 81, 891 is 81.
Highest Common Factor of 81,891 is 81
Step 1: Since 891 > 81, we apply the division lemma to 891 and 81, to get
891 = 81 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 81, the HCF of 81 and 891 is 81
Notice that 81 = HCF(891,81) .
