HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 526, 42425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 526, 42425 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 526, 42425 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 526, 42425 is 1.
HCF(526, 42425) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 526, 42425 is 1.
Step 1: Since 42425 > 526, we apply the division lemma to 42425 and 526, to get
42425 = 526 x 80 + 345
Step 2: Since the reminder 526 ≠ 0, we apply division lemma to 345 and 526, to get
526 = 345 x 1 + 181
Step 3: We consider the new divisor 345 and the new remainder 181, and apply the division lemma to get
345 = 181 x 1 + 164
We consider the new divisor 181 and the new remainder 164,and apply the division lemma to get
181 = 164 x 1 + 17
We consider the new divisor 164 and the new remainder 17,and apply the division lemma to get
164 = 17 x 9 + 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 526 and 42425 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(164,17) = HCF(181,164) = HCF(345,181) = HCF(526,345) = HCF(42425,526) .
Here are some samples of HCF using Euclid's Algorithm calculations.
