HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 534, 729, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 534, 729, 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 534, 729, 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 534, 729, 71 is 1.
HCF(534, 729, 71) = 1
HCF of 534, 729, 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 534, 729, 71 is 1.
Highest Common Factor of 534,729,71 is 1
Step 1: Since 729 > 534, we apply the division lemma to 729 and 534, to get
729 = 534 x 1 + 195
Step 2: Since the reminder 534 ≠ 0, we apply division lemma to 195 and 534, to get
534 = 195 x 2 + 144
Step 3: We consider the new divisor 195 and the new remainder 144, and apply the division lemma to get
195 = 144 x 1 + 51
We consider the new divisor 144 and the new remainder 51,and apply the division lemma to get
144 = 51 x 2 + 42
We consider the new divisor 51 and the new remainder 42,and apply the division lemma to get
51 = 42 x 1 + 9
We consider the new divisor 42 and the new remainder 9,and apply the division lemma to get
42 = 9 x 4 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 534 and 729 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(42,9) = HCF(51,42) = HCF(144,51) = HCF(195,144) = HCF(534,195) = HCF(729,534) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 3, we apply the division lemma to 71 and 3, to get
71 = 3 x 23 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 71 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(71,3) .
