HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 821, 348, 262 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 821, 348, 262 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 821, 348, 262 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 821, 348, 262 is 1.
HCF(821, 348, 262) = 1
HCF of 821, 348, 262 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 821, 348, 262 is 1.
Highest Common Factor of 821,348,262 is 1
Step 1: Since 821 > 348, we apply the division lemma to 821 and 348, to get
821 = 348 x 2 + 125
Step 2: Since the reminder 348 ≠ 0, we apply division lemma to 125 and 348, to get
348 = 125 x 2 + 98
Step 3: We consider the new divisor 125 and the new remainder 98, and apply the division lemma to get
125 = 98 x 1 + 27
We consider the new divisor 98 and the new remainder 27,and apply the division lemma to get
98 = 27 x 3 + 17
We consider the new divisor 27 and the new remainder 17,and apply the division lemma to get
27 = 17 x 1 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 821 and 348 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(98,27) = HCF(125,98) = HCF(348,125) = HCF(821,348) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 262 > 1, we apply the division lemma to 262 and 1, to get
262 = 1 x 262 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 262 is 1
Notice that 1 = HCF(262,1) .
