HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 824, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 824, 521 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 824, 521 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 824, 521 is 1.
HCF(824, 521) = 1
HCF of 824, 521 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 824, 521 is 1.
Highest Common Factor of 824,521 is 1
Step 1: Since 824 > 521, we apply the division lemma to 824 and 521, to get
824 = 521 x 1 + 303
Step 2: Since the reminder 521 ≠ 0, we apply division lemma to 303 and 521, to get
521 = 303 x 1 + 218
Step 3: We consider the new divisor 303 and the new remainder 218, and apply the division lemma to get
303 = 218 x 1 + 85
We consider the new divisor 218 and the new remainder 85,and apply the division lemma to get
218 = 85 x 2 + 48
We consider the new divisor 85 and the new remainder 48,and apply the division lemma to get
85 = 48 x 1 + 37
We consider the new divisor 48 and the new remainder 37,and apply the division lemma to get
48 = 37 x 1 + 11
We consider the new divisor 37 and the new remainder 11,and apply the division lemma to get
37 = 11 x 3 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 824 and 521 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(37,11) = HCF(48,37) = HCF(85,48) = HCF(218,85) = HCF(303,218) = HCF(521,303) = HCF(824,521) .
