HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 362 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 821, 362 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 821, 362 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 821, 362 is 1.
HCF(821, 362) = 1
HCF of 821, 362 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 821, 362 is 1.
Highest Common Factor of 821,362 is 1
Step 1: Since 821 > 362, we apply the division lemma to 821 and 362, to get
821 = 362 x 2 + 97
Step 2: Since the reminder 362 ≠ 0, we apply division lemma to 97 and 362, to get
362 = 97 x 3 + 71
Step 3: We consider the new divisor 97 and the new remainder 71, and apply the division lemma to get
97 = 71 x 1 + 26
We consider the new divisor 71 and the new remainder 26,and apply the division lemma to get
71 = 26 x 2 + 19
We consider the new divisor 26 and the new remainder 19,and apply the division lemma to get
26 = 19 x 1 + 7
We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get
19 = 7 x 2 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 821 and 362 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(26,19) = HCF(71,26) = HCF(97,71) = HCF(362,97) = HCF(821,362) .
