HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 776, 168 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 776, 168 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 997, 776, 168 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 997, 776, 168 is 1.
HCF(997, 776, 168) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 776, 168 is 1.
Step 1: Since 997 > 776, we apply the division lemma to 997 and 776, to get
997 = 776 x 1 + 221
Step 2: Since the reminder 776 ≠ 0, we apply division lemma to 221 and 776, to get
776 = 221 x 3 + 113
Step 3: We consider the new divisor 221 and the new remainder 113, and apply the division lemma to get
221 = 113 x 1 + 108
We consider the new divisor 113 and the new remainder 108,and apply the division lemma to get
113 = 108 x 1 + 5
We consider the new divisor 108 and the new remainder 5,and apply the division lemma to get
108 = 5 x 21 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 997 and 776 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(108,5) = HCF(113,108) = HCF(221,113) = HCF(776,221) = HCF(997,776) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 168 > 1, we apply the division lemma to 168 and 1, to get
168 = 1 x 168 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 168 is 1
Notice that 1 = HCF(168,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
