HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 8263 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 8263 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 981, 8263 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 981, 8263 is 1.
HCF(981, 8263) = 1
HCF of 981, 8263 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 981, 8263 is 1.
Highest Common Factor of 981,8263 is 1
Step 1: Since 8263 > 981, we apply the division lemma to 8263 and 981, to get
8263 = 981 x 8 + 415
Step 2: Since the reminder 981 ≠ 0, we apply division lemma to 415 and 981, to get
981 = 415 x 2 + 151
Step 3: We consider the new divisor 415 and the new remainder 151, and apply the division lemma to get
415 = 151 x 2 + 113
We consider the new divisor 151 and the new remainder 113,and apply the division lemma to get
151 = 113 x 1 + 38
We consider the new divisor 113 and the new remainder 38,and apply the division lemma to get
113 = 38 x 2 + 37
We consider the new divisor 38 and the new remainder 37,and apply the division lemma to get
38 = 37 x 1 + 1
We consider the new divisor 37 and the new remainder 1,and apply the division lemma to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 981 and 8263 is 1
Notice that 1 = HCF(37,1) = HCF(38,37) = HCF(113,38) = HCF(151,113) = HCF(415,151) = HCF(981,415) = HCF(8263,981) .
