HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 997, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 997, 73 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 863, 997, 73 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 863, 997, 73 is 1.
HCF(863, 997, 73) = 1
HCF of 863, 997, 73 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 997, 73 is 1.
Highest Common Factor of 863,997,73 is 1
Step 1: Since 997 > 863, we apply the division lemma to 997 and 863, to get
997 = 863 x 1 + 134
Step 2: Since the reminder 863 ≠ 0, we apply division lemma to 134 and 863, to get
863 = 134 x 6 + 59
Step 3: We consider the new divisor 134 and the new remainder 59, and apply the division lemma to get
134 = 59 x 2 + 16
We consider the new divisor 59 and the new remainder 16,and apply the division lemma to get
59 = 16 x 3 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 997 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(59,16) = HCF(134,59) = HCF(863,134) = HCF(997,863) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73 > 1, we apply the division lemma to 73 and 1, to get
73 = 1 x 73 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73 is 1
Notice that 1 = HCF(73,1) .
