HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 921, 971 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 921, 971 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 921, 971 is 1.
HCF(921, 971) = 1
HCF of 921, 971 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 921, 971 is 1.
Highest Common Factor of 921,971 is 1
Step 1: Since 971 > 921, we apply the division lemma to 971 and 921, to get
971 = 921 x 1 + 50
Step 2: Since the reminder 921 ≠ 0, we apply division lemma to 50 and 921, to get
921 = 50 x 18 + 21
Step 3: We consider the new divisor 50 and the new remainder 21, and apply the division lemma to get
50 = 21 x 2 + 8
We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get
21 = 8 x 2 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 921 and 971 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(50,21) = HCF(921,50) = HCF(971,921) .
