HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 861, 997, 367 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 861, 997, 367 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 861, 997, 367 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 861, 997, 367 is 1.
HCF(861, 997, 367) = 1
HCF of 861, 997, 367 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 861, 997, 367 is 1.
Highest Common Factor of 861,997,367 is 1
Step 1: Since 997 > 861, we apply the division lemma to 997 and 861, to get
997 = 861 x 1 + 136
Step 2: Since the reminder 861 ≠ 0, we apply division lemma to 136 and 861, to get
861 = 136 x 6 + 45
Step 3: We consider the new divisor 136 and the new remainder 45, and apply the division lemma to get
136 = 45 x 3 + 1
We consider the new divisor 45 and the new remainder 1, and apply the division lemma to get
45 = 1 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 861 and 997 is 1
Notice that 1 = HCF(45,1) = HCF(136,45) = HCF(861,136) = HCF(997,861) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 367 > 1, we apply the division lemma to 367 and 1, to get
367 = 1 x 367 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 367 is 1
Notice that 1 = HCF(367,1) .
