HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 632, 171, 823 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 632, 171, 823 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 632, 171, 823 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 632, 171, 823 is 1.
HCF(632, 171, 823) = 1
HCF of 632, 171, 823 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 632, 171, 823 is 1.
Highest Common Factor of 632,171,823 is 1
Step 1: Since 632 > 171, we apply the division lemma to 632 and 171, to get
632 = 171 x 3 + 119
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 119 and 171, to get
171 = 119 x 1 + 52
Step 3: We consider the new divisor 119 and the new remainder 52, and apply the division lemma to get
119 = 52 x 2 + 15
We consider the new divisor 52 and the new remainder 15,and apply the division lemma to get
52 = 15 x 3 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 632 and 171 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(52,15) = HCF(119,52) = HCF(171,119) = HCF(632,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 823 > 1, we apply the division lemma to 823 and 1, to get
823 = 1 x 823 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 823 is 1
Notice that 1 = HCF(823,1) .
