HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 80, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 361, 80, 166 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 361, 80, 166 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 361, 80, 166 is 1.
HCF(361, 80, 166) = 1
HCF of 361, 80, 166 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 361, 80, 166 is 1.
Highest Common Factor of 361,80,166 is 1
Step 1: Since 361 > 80, we apply the division lemma to 361 and 80, to get
361 = 80 x 4 + 41
Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 41 and 80, to get
80 = 41 x 1 + 39
Step 3: We consider the new divisor 41 and the new remainder 39, and apply the division lemma to get
41 = 39 x 1 + 2
We consider the new divisor 39 and the new remainder 2,and apply the division lemma to get
39 = 2 x 19 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 361 and 80 is 1
Notice that 1 = HCF(2,1) = HCF(39,2) = HCF(41,39) = HCF(80,41) = HCF(361,80) .
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) .
