HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 746, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 663, 746, 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 663, 746, 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 663, 746, 71 is 1.
HCF(663, 746, 71) = 1
HCF of 663, 746, 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 663, 746, 71 is 1.
Highest Common Factor of 663,746,71 is 1
Step 1: Since 746 > 663, we apply the division lemma to 746 and 663, to get
746 = 663 x 1 + 83
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 83 and 663, to get
663 = 83 x 7 + 82
Step 3: We consider the new divisor 83 and the new remainder 82, and apply the division lemma to get
83 = 82 x 1 + 1
We consider the new divisor 82 and the new remainder 1, and apply the division lemma to get
82 = 1 x 82 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 663 and 746 is 1
Notice that 1 = HCF(82,1) = HCF(83,82) = HCF(663,83) = HCF(746,663) .
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) .
