HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 171, 962, 34 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 171, 962, 34 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, 962, 34 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, 962, 34 is 1.
HCF(171, 962, 34) = 1
HCF of 171, 962, 34 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, 962, 34 is 1.
Highest Common Factor of 171,962,34 is 1
Step 1: Since 962 > 171, we apply the division lemma to 962 and 171, to get
962 = 171 x 5 + 107
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 107 and 171, to get
171 = 107 x 1 + 64
Step 3: We consider the new divisor 107 and the new remainder 64, and apply the division lemma to get
107 = 64 x 1 + 43
We consider the new divisor 64 and the new remainder 43,and apply the division lemma to get
64 = 43 x 1 + 21
We consider the new divisor 43 and the new remainder 21,and apply the division lemma to get
43 = 21 x 2 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 171 and 962 is 1
Notice that 1 = HCF(21,1) = HCF(43,21) = HCF(64,43) = HCF(107,64) = HCF(171,107) = HCF(962,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 34 > 1, we apply the division lemma to 34 and 1, to get
34 = 1 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 34 is 1
Notice that 1 = HCF(34,1) .
