HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 943, 694, 866 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 943, 694, 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 943, 694, 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 943, 694, 866 is 1.
HCF(943, 694, 866) = 1
HCF of 943, 694, 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 943, 694, 866 is 1.
Highest Common Factor of 943,694,866 is 1
Step 1: Since 943 > 694, we apply the division lemma to 943 and 694, to get
943 = 694 x 1 + 249
Step 2: Since the reminder 694 ≠ 0, we apply division lemma to 249 and 694, to get
694 = 249 x 2 + 196
Step 3: We consider the new divisor 249 and the new remainder 196, and apply the division lemma to get
249 = 196 x 1 + 53
We consider the new divisor 196 and the new remainder 53,and apply the division lemma to get
196 = 53 x 3 + 37
We consider the new divisor 53 and the new remainder 37,and apply the division lemma to get
53 = 37 x 1 + 16
We consider the new divisor 37 and the new remainder 16,and apply the division lemma to get
37 = 16 x 2 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 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 943 and 694 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(37,16) = HCF(53,37) = HCF(196,53) = HCF(249,196) = HCF(694,249) = HCF(943,694) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 866 > 1, we apply the division lemma to 866 and 1, to get
866 = 1 x 866 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 866 is 1
Notice that 1 = HCF(866,1) .
