HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 177, 167 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 177, 167 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 905, 177, 167 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 905, 177, 167 is 1.
HCF(905, 177, 167) = 1
HCF of 905, 177, 167 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 905, 177, 167 is 1.
Highest Common Factor of 905,177,167 is 1
Step 1: Since 905 > 177, we apply the division lemma to 905 and 177, to get
905 = 177 x 5 + 20
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 20 and 177, to get
177 = 20 x 8 + 17
Step 3: We consider the new divisor 20 and the new remainder 17, and apply the division lemma to get
20 = 17 x 1 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 905 and 177 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(177,20) = HCF(905,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 167 > 1, we apply the division lemma to 167 and 1, to get
167 = 1 x 167 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 167 is 1
Notice that 1 = HCF(167,1) .
