HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 853 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 477, 853 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 477, 853 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 477, 853 is 1.
HCF(477, 853) = 1
HCF of 477, 853 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 477, 853 is 1.
Highest Common Factor of 477,853 is 1
Step 1: Since 853 > 477, we apply the division lemma to 853 and 477, to get
853 = 477 x 1 + 376
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 376 and 477, to get
477 = 376 x 1 + 101
Step 3: We consider the new divisor 376 and the new remainder 101, and apply the division lemma to get
376 = 101 x 3 + 73
We consider the new divisor 101 and the new remainder 73,and apply the division lemma to get
101 = 73 x 1 + 28
We consider the new divisor 73 and the new remainder 28,and apply the division lemma to get
73 = 28 x 2 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 477 and 853 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(73,28) = HCF(101,73) = HCF(376,101) = HCF(477,376) = HCF(853,477) .
