HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 617, 191, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 617, 191, 117 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 617, 191, 117 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 617, 191, 117 is 1.
HCF(617, 191, 117) = 1
HCF of 617, 191, 117 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 617, 191, 117 is 1.
Highest Common Factor of 617,191,117 is 1
Step 1: Since 617 > 191, we apply the division lemma to 617 and 191, to get
617 = 191 x 3 + 44
Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 44 and 191, to get
191 = 44 x 4 + 15
Step 3: We consider the new divisor 44 and the new remainder 15, and apply the division lemma to get
44 = 15 x 2 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 617 and 191 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(44,15) = HCF(191,44) = HCF(617,191) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get
117 = 1 x 117 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1
Notice that 1 = HCF(117,1) .
