HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 171, 963 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 171, 963 is 9 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, 963 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, 963 is 9.
HCF(171, 963) = 9
HCF of 171, 963 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, 963 is 9.
Highest Common Factor of 171,963 is 9
Step 1: Since 963 > 171, we apply the division lemma to 963 and 171, to get
963 = 171 x 5 + 108
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 108 and 171, to get
171 = 108 x 1 + 63
Step 3: We consider the new divisor 108 and the new remainder 63, and apply the division lemma to get
108 = 63 x 1 + 45
We consider the new divisor 63 and the new remainder 45,and apply the division lemma to get
63 = 45 x 1 + 18
We consider the new divisor 45 and the new remainder 18,and apply the division lemma to get
45 = 18 x 2 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 171 and 963 is 9
Notice that 9 = HCF(18,9) = HCF(45,18) = HCF(63,45) = HCF(108,63) = HCF(171,108) = HCF(963,171) .
