HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 982, 271, 368 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 982, 271, 368 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 982, 271, 368 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 982, 271, 368 is 1.
HCF(982, 271, 368) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 982, 271, 368 is 1.
Step 1: Since 982 > 271, we apply the division lemma to 982 and 271, to get
982 = 271 x 3 + 169
Step 2: Since the reminder 271 ≠ 0, we apply division lemma to 169 and 271, to get
271 = 169 x 1 + 102
Step 3: We consider the new divisor 169 and the new remainder 102, and apply the division lemma to get
169 = 102 x 1 + 67
We consider the new divisor 102 and the new remainder 67,and apply the division lemma to get
102 = 67 x 1 + 35
We consider the new divisor 67 and the new remainder 35,and apply the division lemma to get
67 = 35 x 1 + 32
We consider the new divisor 35 and the new remainder 32,and apply the division lemma to get
35 = 32 x 1 + 3
We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get
32 = 3 x 10 + 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 982 and 271 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(35,32) = HCF(67,35) = HCF(102,67) = HCF(169,102) = HCF(271,169) = HCF(982,271) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 368 > 1, we apply the division lemma to 368 and 1, to get
368 = 1 x 368 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 368 is 1
Notice that 1 = HCF(368,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
