HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 985, 177, 271 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 985, 177, 271 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 985, 177, 271 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 985, 177, 271 is 1.
HCF(985, 177, 271) = 1
HCF of 985, 177, 271 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 985, 177, 271 is 1.
Highest Common Factor of 985,177,271 is 1
Step 1: Since 985 > 177, we apply the division lemma to 985 and 177, to get
985 = 177 x 5 + 100
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 100 and 177, to get
177 = 100 x 1 + 77
Step 3: We consider the new divisor 100 and the new remainder 77, and apply the division lemma to get
100 = 77 x 1 + 23
We consider the new divisor 77 and the new remainder 23,and apply the division lemma to get
77 = 23 x 3 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 985 and 177 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(77,23) = HCF(100,77) = HCF(177,100) = HCF(985,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 271 > 1, we apply the division lemma to 271 and 1, to get
271 = 1 x 271 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 271 is 1
Notice that 1 = HCF(271,1) .
