HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 67, 497, 178 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 67, 497, 178 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 67, 497, 178 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 67, 497, 178 is 1.
HCF(67, 497, 178) = 1
HCF of 67, 497, 178 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 67, 497, 178 is 1.
Highest Common Factor of 67,497,178 is 1
Step 1: Since 497 > 67, we apply the division lemma to 497 and 67, to get
497 = 67 x 7 + 28
Step 2: Since the reminder 67 ≠ 0, we apply division lemma to 28 and 67, to get
67 = 28 x 2 + 11
Step 3: We consider the new divisor 28 and the new remainder 11, and apply the division lemma to get
28 = 11 x 2 + 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 67 and 497 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(28,11) = HCF(67,28) = HCF(497,67) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 178 > 1, we apply the division lemma to 178 and 1, to get
178 = 1 x 178 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 178 is 1
Notice that 1 = HCF(178,1) .
