HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 809, 921 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 809, 921 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 809, 921 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 809, 921 is 1.
HCF(809, 921) = 1
HCF of 809, 921 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 809, 921 is 1.
Highest Common Factor of 809,921 is 1
Step 1: Since 921 > 809, we apply the division lemma to 921 and 809, to get
921 = 809 x 1 + 112
Step 2: Since the reminder 809 ≠ 0, we apply division lemma to 112 and 809, to get
809 = 112 x 7 + 25
Step 3: We consider the new divisor 112 and the new remainder 25, and apply the division lemma to get
112 = 25 x 4 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 809 and 921 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(112,25) = HCF(809,112) = HCF(921,809) .
