HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 171, 798, 146 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 171, 798, 146 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 171, 798, 146 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 171, 798, 146 is 1.
HCF(171, 798, 146) = 1
HCF of 171, 798, 146 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 171, 798, 146 is 1.
Highest Common Factor of 171,798,146 is 1
Step 1: Since 798 > 171, we apply the division lemma to 798 and 171, to get
798 = 171 x 4 + 114
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 114 and 171, to get
171 = 114 x 1 + 57
Step 3: We consider the new divisor 114 and the new remainder 57, and apply the division lemma to get
114 = 57 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 57, the HCF of 171 and 798 is 57
Notice that 57 = HCF(114,57) = HCF(171,114) = HCF(798,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 146 > 57, we apply the division lemma to 146 and 57, to get
146 = 57 x 2 + 32
Step 2: Since the reminder 57 ≠ 0, we apply division lemma to 32 and 57, to get
57 = 32 x 1 + 25
Step 3: 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 57 and 146 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(32,25) = HCF(57,32) = HCF(146,57) .
