HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 196, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 196, 491 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 320, 196, 491 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 320, 196, 491 is 1.
HCF(320, 196, 491) = 1
HCF of 320, 196, 491 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 196, 491 is 1.
Highest Common Factor of 320,196,491 is 1
Step 1: Since 320 > 196, we apply the division lemma to 320 and 196, to get
320 = 196 x 1 + 124
Step 2: Since the reminder 196 ≠ 0, we apply division lemma to 124 and 196, to get
196 = 124 x 1 + 72
Step 3: We consider the new divisor 124 and the new remainder 72, and apply the division lemma to get
124 = 72 x 1 + 52
We consider the new divisor 72 and the new remainder 52,and apply the division lemma to get
72 = 52 x 1 + 20
We consider the new divisor 52 and the new remainder 20,and apply the division lemma to get
52 = 20 x 2 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 320 and 196 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(52,20) = HCF(72,52) = HCF(124,72) = HCF(196,124) = HCF(320,196) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 491 > 4, we apply the division lemma to 491 and 4, to get
491 = 4 x 122 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 491 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(491,4) .
