HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7867, 7420 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7867, 7420 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 7867, 7420 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 7867, 7420 is 1.
HCF(7867, 7420) = 1
HCF of 7867, 7420 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7867, 7420 is 1.
Highest Common Factor of 7867,7420 is 1
Step 1: Since 7867 > 7420, we apply the division lemma to 7867 and 7420, to get
7867 = 7420 x 1 + 447
Step 2: Since the reminder 7420 ≠ 0, we apply division lemma to 447 and 7420, to get
7420 = 447 x 16 + 268
Step 3: We consider the new divisor 447 and the new remainder 268, and apply the division lemma to get
447 = 268 x 1 + 179
We consider the new divisor 268 and the new remainder 179,and apply the division lemma to get
268 = 179 x 1 + 89
We consider the new divisor 179 and the new remainder 89,and apply the division lemma to get
179 = 89 x 2 + 1
We consider the new divisor 89 and the new remainder 1,and apply the division lemma to get
89 = 1 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7867 and 7420 is 1
Notice that 1 = HCF(89,1) = HCF(179,89) = HCF(268,179) = HCF(447,268) = HCF(7420,447) = HCF(7867,7420) .
