HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 956, 691, 83 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 956, 691, 83 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 956, 691, 83 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 956, 691, 83 is 1.
HCF(956, 691, 83) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 956, 691, 83 is 1.
Step 1: Since 956 > 691, we apply the division lemma to 956 and 691, to get
956 = 691 x 1 + 265
Step 2: Since the reminder 691 ≠ 0, we apply division lemma to 265 and 691, to get
691 = 265 x 2 + 161
Step 3: We consider the new divisor 265 and the new remainder 161, and apply the division lemma to get
265 = 161 x 1 + 104
We consider the new divisor 161 and the new remainder 104,and apply the division lemma to get
161 = 104 x 1 + 57
We consider the new divisor 104 and the new remainder 57,and apply the division lemma to get
104 = 57 x 1 + 47
We consider the new divisor 57 and the new remainder 47,and apply the division lemma to get
57 = 47 x 1 + 10
We consider the new divisor 47 and the new remainder 10,and apply the division lemma to get
47 = 10 x 4 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 956 and 691 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(47,10) = HCF(57,47) = HCF(104,57) = HCF(161,104) = HCF(265,161) = HCF(691,265) = HCF(956,691) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 83 > 1, we apply the division lemma to 83 and 1, to get
83 = 1 x 83 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 83 is 1
Notice that 1 = HCF(83,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
