HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 235, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 851, 235, 117 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 851, 235, 117 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 851, 235, 117 is 1.
HCF(851, 235, 117) = 1
HCF of 851, 235, 117 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 851, 235, 117 is 1.
Highest Common Factor of 851,235,117 is 1
Step 1: Since 851 > 235, we apply the division lemma to 851 and 235, to get
851 = 235 x 3 + 146
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 146 and 235, to get
235 = 146 x 1 + 89
Step 3: We consider the new divisor 146 and the new remainder 89, and apply the division lemma to get
146 = 89 x 1 + 57
We consider the new divisor 89 and the new remainder 57,and apply the division lemma to get
89 = 57 x 1 + 32
We consider the new divisor 57 and the new remainder 32,and apply the division lemma to get
57 = 32 x 1 + 25
We consider the new divisor 32 and the new remainder 25,and apply the division lemma to get
32 = 25 x 1 + 7
We consider the new divisor 25 and the new remainder 7,and apply the division lemma to get
25 = 7 x 3 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 851 and 235 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(32,25) = HCF(57,32) = HCF(89,57) = HCF(146,89) = HCF(235,146) = HCF(851,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 117 > 1, we apply the division lemma to 117 and 1, to get
117 = 1 x 117 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 117 is 1
Notice that 1 = HCF(117,1) .
