HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 482, 646, 38, 826 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 482, 646, 38, 826 is 2 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 482, 646, 38, 826 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 482, 646, 38, 826 is 2.
HCF(482, 646, 38, 826) = 2
HCF of 482, 646, 38, 826 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 482, 646, 38, 826 is 2.
Highest Common Factor of 482,646,38,826 is 2
Step 1: Since 646 > 482, we apply the division lemma to 646 and 482, to get
646 = 482 x 1 + 164
Step 2: Since the reminder 482 ≠ 0, we apply division lemma to 164 and 482, to get
482 = 164 x 2 + 154
Step 3: We consider the new divisor 164 and the new remainder 154, and apply the division lemma to get
164 = 154 x 1 + 10
We consider the new divisor 154 and the new remainder 10,and apply the division lemma to get
154 = 10 x 15 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 482 and 646 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(154,10) = HCF(164,154) = HCF(482,164) = HCF(646,482) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 2, we apply the division lemma to 38 and 2, to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 38 is 2
Notice that 2 = HCF(38,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 826 > 2, we apply the division lemma to 826 and 2, to get
826 = 2 x 413 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 826 is 2
Notice that 2 = HCF(826,2) .
