HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 697, 193, 211, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 697, 193, 211, 71 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 697, 193, 211, 71 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 697, 193, 211, 71 is 1.
HCF(697, 193, 211, 71) = 1
HCF of 697, 193, 211, 71 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 697, 193, 211, 71 is 1.
Highest Common Factor of 697,193,211,71 is 1
Step 1: Since 697 > 193, we apply the division lemma to 697 and 193, to get
697 = 193 x 3 + 118
Step 2: Since the reminder 193 ≠ 0, we apply division lemma to 118 and 193, to get
193 = 118 x 1 + 75
Step 3: We consider the new divisor 118 and the new remainder 75, and apply the division lemma to get
118 = 75 x 1 + 43
We consider the new divisor 75 and the new remainder 43,and apply the division lemma to get
75 = 43 x 1 + 32
We consider the new divisor 43 and the new remainder 32,and apply the division lemma to get
43 = 32 x 1 + 11
We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get
32 = 11 x 2 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 697 and 193 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(75,43) = HCF(118,75) = HCF(193,118) = HCF(697,193) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 211 > 1, we apply the division lemma to 211 and 1, to get
211 = 1 x 211 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 211 is 1
Notice that 1 = HCF(211,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 1, we apply the division lemma to 71 and 1, to get
71 = 1 x 71 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 71 is 1
Notice that 1 = HCF(71,1) .
