HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 171, 238, 601 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 171, 238, 601 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 171, 238, 601 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 171, 238, 601 is 1.
HCF(171, 238, 601) = 1
HCF of 171, 238, 601 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 171, 238, 601 is 1.
Highest Common Factor of 171,238,601 is 1
Step 1: Since 238 > 171, we apply the division lemma to 238 and 171, to get
238 = 171 x 1 + 67
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 67 and 171, to get
171 = 67 x 2 + 37
Step 3: We consider the new divisor 67 and the new remainder 37, and apply the division lemma to get
67 = 37 x 1 + 30
We consider the new divisor 37 and the new remainder 30,and apply the division lemma to get
37 = 30 x 1 + 7
We consider the new divisor 30 and the new remainder 7,and apply the division lemma to get
30 = 7 x 4 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 171 and 238 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(30,7) = HCF(37,30) = HCF(67,37) = HCF(171,67) = HCF(238,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 601 > 1, we apply the division lemma to 601 and 1, to get
601 = 1 x 601 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 601 is 1
Notice that 1 = HCF(601,1) .
