HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 897, 721 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 897, 721 is 1 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 897, 721 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 897, 721 is 1.
HCF(897, 721) = 1
HCF of 897, 721 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 897, 721 is 1.
Highest Common Factor of 897,721 is 1
Step 1: Since 897 > 721, we apply the division lemma to 897 and 721, to get
897 = 721 x 1 + 176
Step 2: Since the reminder 721 ≠ 0, we apply division lemma to 176 and 721, to get
721 = 176 x 4 + 17
Step 3: We consider the new divisor 176 and the new remainder 17, and apply the division lemma to get
176 = 17 x 10 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 897 and 721 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(176,17) = HCF(721,176) = HCF(897,721) .
