HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 465, 636, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 465, 636, 997 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 465, 636, 997 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 465, 636, 997 is 1.
HCF(465, 636, 997) = 1
HCF of 465, 636, 997 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 465, 636, 997 is 1.
Highest Common Factor of 465,636,997 is 1
Step 1: Since 636 > 465, we apply the division lemma to 636 and 465, to get
636 = 465 x 1 + 171
Step 2: Since the reminder 465 ≠ 0, we apply division lemma to 171 and 465, to get
465 = 171 x 2 + 123
Step 3: We consider the new divisor 171 and the new remainder 123, and apply the division lemma to get
171 = 123 x 1 + 48
We consider the new divisor 123 and the new remainder 48,and apply the division lemma to get
123 = 48 x 2 + 27
We consider the new divisor 48 and the new remainder 27,and apply the division lemma to get
48 = 27 x 1 + 21
We consider the new divisor 27 and the new remainder 21,and apply the division lemma to get
27 = 21 x 1 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 465 and 636 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(27,21) = HCF(48,27) = HCF(123,48) = HCF(171,123) = HCF(465,171) = HCF(636,465) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 997 > 3, we apply the division lemma to 997 and 3, to get
997 = 3 x 332 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 997 is 1
Notice that 1 = HCF(3,1) = HCF(997,3) .
