HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 281 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 281 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 791, 281 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 791, 281 is 1.
HCF(791, 281) = 1
HCF of 791, 281 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 281 is 1.
Highest Common Factor of 791,281 is 1
Step 1: Since 791 > 281, we apply the division lemma to 791 and 281, to get
791 = 281 x 2 + 229
Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 229 and 281, to get
281 = 229 x 1 + 52
Step 3: We consider the new divisor 229 and the new remainder 52, and apply the division lemma to get
229 = 52 x 4 + 21
We consider the new divisor 52 and the new remainder 21,and apply the division lemma to get
52 = 21 x 2 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 281 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(52,21) = HCF(229,52) = HCF(281,229) = HCF(791,281) .
