HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 322, 549, 166, 769 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 322, 549, 166, 769 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 322, 549, 166, 769 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 322, 549, 166, 769 is 1.
HCF(322, 549, 166, 769) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 322, 549, 166, 769 is 1.
Step 1: Since 549 > 322, we apply the division lemma to 549 and 322, to get
549 = 322 x 1 + 227
Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 227 and 322, to get
322 = 227 x 1 + 95
Step 3: We consider the new divisor 227 and the new remainder 95, and apply the division lemma to get
227 = 95 x 2 + 37
We consider the new divisor 95 and the new remainder 37,and apply the division lemma to get
95 = 37 x 2 + 21
We consider the new divisor 37 and the new remainder 21,and apply the division lemma to get
37 = 21 x 1 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 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 322 and 549 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(37,21) = HCF(95,37) = HCF(227,95) = HCF(322,227) = HCF(549,322) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 166 > 1, we apply the division lemma to 166 and 1, to get
166 = 1 x 166 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 166 is 1
Notice that 1 = HCF(166,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 769 > 1, we apply the division lemma to 769 and 1, to get
769 = 1 x 769 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 769 is 1
Notice that 1 = HCF(769,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
