HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 134, 116 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 221, 134, 116 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 221, 134, 116 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 221, 134, 116 is 1.
HCF(221, 134, 116) = 1
HCF of 221, 134, 116 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 221, 134, 116 is 1.
Highest Common Factor of 221,134,116 is 1
Step 1: Since 221 > 134, we apply the division lemma to 221 and 134, to get
221 = 134 x 1 + 87
Step 2: Since the reminder 134 ≠ 0, we apply division lemma to 87 and 134, to get
134 = 87 x 1 + 47
Step 3: We consider the new divisor 87 and the new remainder 47, and apply the division lemma to get
87 = 47 x 1 + 40
We consider the new divisor 47 and the new remainder 40,and apply the division lemma to get
47 = 40 x 1 + 7
We consider the new divisor 40 and the new remainder 7,and apply the division lemma to get
40 = 7 x 5 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 221 and 134 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(40,7) = HCF(47,40) = HCF(87,47) = HCF(134,87) = HCF(221,134) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 116 > 1, we apply the division lemma to 116 and 1, to get
116 = 1 x 116 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 116 is 1
Notice that 1 = HCF(116,1) .
