HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 853, 47821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 853, 47821 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 853, 47821 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 853, 47821 is 1.
HCF(853, 47821) = 1
HCF of 853, 47821 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 853, 47821 is 1.
Highest Common Factor of 853,47821 is 1
Step 1: Since 47821 > 853, we apply the division lemma to 47821 and 853, to get
47821 = 853 x 56 + 53
Step 2: Since the reminder 853 ≠ 0, we apply division lemma to 53 and 853, to get
853 = 53 x 16 + 5
Step 3: We consider the new divisor 53 and the new remainder 5, and apply the division lemma to get
53 = 5 x 10 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 853 and 47821 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(53,5) = HCF(853,53) = HCF(47821,853) .
