HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 836, 329, 697 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 836, 329, 697 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 836, 329, 697 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 836, 329, 697 is 1.
HCF(836, 329, 697) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 836, 329, 697 is 1.
Step 1: Since 836 > 329, we apply the division lemma to 836 and 329, to get
836 = 329 x 2 + 178
Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 178 and 329, to get
329 = 178 x 1 + 151
Step 3: We consider the new divisor 178 and the new remainder 151, and apply the division lemma to get
178 = 151 x 1 + 27
We consider the new divisor 151 and the new remainder 27,and apply the division lemma to get
151 = 27 x 5 + 16
We consider the new divisor 27 and the new remainder 16,and apply the division lemma to get
27 = 16 x 1 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 836 and 329 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(151,27) = HCF(178,151) = HCF(329,178) = HCF(836,329) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 697 > 1, we apply the division lemma to 697 and 1, to get
697 = 1 x 697 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 697 is 1
Notice that 1 = HCF(697,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
