HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 56, 97, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 70, 56, 97, 191 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 70, 56, 97, 191 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 70, 56, 97, 191 is 1.
HCF(70, 56, 97, 191) = 1
HCF of 70, 56, 97, 191 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 70, 56, 97, 191 is 1.
Highest Common Factor of 70,56,97,191 is 1
Step 1: Since 70 > 56, we apply the division lemma to 70 and 56, to get
70 = 56 x 1 + 14
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 14 and 56, to get
56 = 14 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 70 and 56 is 14
Notice that 14 = HCF(56,14) = HCF(70,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 97 > 14, we apply the division lemma to 97 and 14, to get
97 = 14 x 6 + 13
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 13 and 14, to get
14 = 13 x 1 + 1
Step 3: We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 97 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(97,14) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 191 > 1, we apply the division lemma to 191 and 1, to get
191 = 1 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 191 is 1
Notice that 1 = HCF(191,1) .
