HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 174, 774 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 396, 174, 774 is 6 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 396, 174, 774 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 396, 174, 774 is 6.
HCF(396, 174, 774) = 6
HCF of 396, 174, 774 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 396, 174, 774 is 6.
Highest Common Factor of 396,174,774 is 6
Step 1: Since 396 > 174, we apply the division lemma to 396 and 174, to get
396 = 174 x 2 + 48
Step 2: Since the reminder 174 ≠ 0, we apply division lemma to 48 and 174, to get
174 = 48 x 3 + 30
Step 3: We consider the new divisor 48 and the new remainder 30, and apply the division lemma to get
48 = 30 x 1 + 18
We consider the new divisor 30 and the new remainder 18,and apply the division lemma to get
30 = 18 x 1 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 396 and 174 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(48,30) = HCF(174,48) = HCF(396,174) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 774 > 6, we apply the division lemma to 774 and 6, to get
774 = 6 x 129 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 774 is 6
Notice that 6 = HCF(774,6) .
