HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 984, 171, 11 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 984, 171, 11 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 984, 171, 11 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 984, 171, 11 is 1.
HCF(984, 171, 11) = 1
HCF of 984, 171, 11 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 984, 171, 11 is 1.
Highest Common Factor of 984,171,11 is 1
Step 1: Since 984 > 171, we apply the division lemma to 984 and 171, to get
984 = 171 x 5 + 129
Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 129 and 171, to get
171 = 129 x 1 + 42
Step 3: We consider the new divisor 129 and the new remainder 42, and apply the division lemma to get
129 = 42 x 3 + 3
We consider the new divisor 42 and the new remainder 3, and apply the division lemma to get
42 = 3 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 984 and 171 is 3
Notice that 3 = HCF(42,3) = HCF(129,42) = HCF(171,129) = HCF(984,171) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 11 > 3, we apply the division lemma to 11 and 3, to get
11 = 3 x 3 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 11 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) .
