HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 866 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 866 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 785, 866 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 785, 866 is 1.
HCF(785, 866) = 1
HCF of 785, 866 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 866 is 1.
Highest Common Factor of 785,866 is 1
Step 1: Since 866 > 785, we apply the division lemma to 866 and 785, to get
866 = 785 x 1 + 81
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 81 and 785, to get
785 = 81 x 9 + 56
Step 3: We consider the new divisor 81 and the new remainder 56, and apply the division lemma to get
81 = 56 x 1 + 25
We consider the new divisor 56 and the new remainder 25,and apply the division lemma to get
56 = 25 x 2 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 785 and 866 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(56,25) = HCF(81,56) = HCF(785,81) = HCF(866,785) .
