HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 711, 538, 43 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 711, 538, 43 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 711, 538, 43 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 711, 538, 43 is 1.
HCF(711, 538, 43) = 1
HCF of 711, 538, 43 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 711, 538, 43 is 1.
Highest Common Factor of 711,538,43 is 1
Step 1: Since 711 > 538, we apply the division lemma to 711 and 538, to get
711 = 538 x 1 + 173
Step 2: Since the reminder 538 ≠ 0, we apply division lemma to 173 and 538, to get
538 = 173 x 3 + 19
Step 3: We consider the new divisor 173 and the new remainder 19, and apply the division lemma to get
173 = 19 x 9 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 711 and 538 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(173,19) = HCF(538,173) = HCF(711,538) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 43 > 1, we apply the division lemma to 43 and 1, to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 43 is 1
Notice that 1 = HCF(43,1) .
