HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 539, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 170, 539, 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 170, 539, 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 170, 539, 166 is 1.
HCF(170, 539, 166) = 1
HCF of 170, 539, 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 170, 539, 166 is 1.
Highest Common Factor of 170,539,166 is 1
Step 1: Since 539 > 170, we apply the division lemma to 539 and 170, to get
539 = 170 x 3 + 29
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 29 and 170, to get
170 = 29 x 5 + 25
Step 3: We consider the new divisor 29 and the new remainder 25, and apply the division lemma to get
29 = 25 x 1 + 4
We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get
25 = 4 x 6 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 170 and 539 is 1
Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(170,29) = HCF(539,170) .
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) .
