HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 836, 671, 771 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 836, 671, 771 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, 671, 771 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, 671, 771 is 1.
HCF(836, 671, 771) = 1
HCF of 836, 671, 771 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 836, 671, 771 is 1.
Highest Common Factor of 836,671,771 is 1
Step 1: Since 836 > 671, we apply the division lemma to 836 and 671, to get
836 = 671 x 1 + 165
Step 2: Since the reminder 671 ≠ 0, we apply division lemma to 165 and 671, to get
671 = 165 x 4 + 11
Step 3: We consider the new divisor 165 and the new remainder 11, and apply the division lemma to get
165 = 11 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 836 and 671 is 11
Notice that 11 = HCF(165,11) = HCF(671,165) = HCF(836,671) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 11, we apply the division lemma to 771 and 11, to get
771 = 11 x 70 + 1
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 1 and 11, to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 771 is 1
Notice that 1 = HCF(11,1) = HCF(771,11) .
