HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8421, 8501 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8421, 8501 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 8421, 8501 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 8421, 8501 is 1.
HCF(8421, 8501) = 1
HCF of 8421, 8501 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8421, 8501 is 1.
Highest Common Factor of 8421,8501 is 1
Step 1: Since 8501 > 8421, we apply the division lemma to 8501 and 8421, to get
8501 = 8421 x 1 + 80
Step 2: Since the reminder 8421 ≠ 0, we apply division lemma to 80 and 8421, to get
8421 = 80 x 105 + 21
Step 3: We consider the new divisor 80 and the new remainder 21, and apply the division lemma to get
80 = 21 x 3 + 17
We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get
21 = 17 x 1 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 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 8421 and 8501 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(80,21) = HCF(8421,80) = HCF(8501,8421) .
