HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 81, 699 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 396, 81, 699 is 3 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 396, 81, 699 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 396, 81, 699 is 3.
HCF(396, 81, 699) = 3
HCF of 396, 81, 699 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 396, 81, 699 is 3.
Highest Common Factor of 396,81,699 is 3
Step 1: Since 396 > 81, we apply the division lemma to 396 and 81, to get
396 = 81 x 4 + 72
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 72 and 81, to get
81 = 72 x 1 + 9
Step 3: We consider the new divisor 72 and the new remainder 9, and apply the division lemma to get
72 = 9 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 396 and 81 is 9
Notice that 9 = HCF(72,9) = HCF(81,72) = HCF(396,81) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 699 > 9, we apply the division lemma to 699 and 9, to get
699 = 9 x 77 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 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 9 and 699 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(699,9) .
