HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 2356 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 821, 2356 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, 2356 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, 2356 is 1.
HCF(821, 2356) = 1
HCF of 821, 2356 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, 2356 is 1.
Highest Common Factor of 821,2356 is 1
Step 1: Since 2356 > 821, we apply the division lemma to 2356 and 821, to get
2356 = 821 x 2 + 714
Step 2: Since the reminder 821 ≠ 0, we apply division lemma to 714 and 821, to get
821 = 714 x 1 + 107
Step 3: We consider the new divisor 714 and the new remainder 107, and apply the division lemma to get
714 = 107 x 6 + 72
We consider the new divisor 107 and the new remainder 72,and apply the division lemma to get
107 = 72 x 1 + 35
We consider the new divisor 72 and the new remainder 35,and apply the division lemma to get
72 = 35 x 2 + 2
We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get
35 = 2 x 17 + 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 2356 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(72,35) = HCF(107,72) = HCF(714,107) = HCF(821,714) = HCF(2356,821) .
