HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 761, 9871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 761, 9871 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 761, 9871 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 761, 9871 is 1.
HCF(761, 9871) = 1
HCF of 761, 9871 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 761, 9871 is 1.
Highest Common Factor of 761,9871 is 1
Step 1: Since 9871 > 761, we apply the division lemma to 9871 and 761, to get
9871 = 761 x 12 + 739
Step 2: Since the reminder 761 ≠ 0, we apply division lemma to 739 and 761, to get
761 = 739 x 1 + 22
Step 3: We consider the new divisor 739 and the new remainder 22, and apply the division lemma to get
739 = 22 x 33 + 13
We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get
22 = 13 x 1 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 761 and 9871 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(739,22) = HCF(761,739) = HCF(9871,761) .
