HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 97, 65, 55, 118 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 97, 65, 55, 118 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 97, 65, 55, 118 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 97, 65, 55, 118 is 1.
HCF(97, 65, 55, 118) = 1
HCF of 97, 65, 55, 118 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 97, 65, 55, 118 is 1.
Highest Common Factor of 97,65,55,118 is 1
Step 1: Since 97 > 65, we apply the division lemma to 97 and 65, to get
97 = 65 x 1 + 32
Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 32 and 65, to get
65 = 32 x 2 + 1
Step 3: We consider the new divisor 32 and the new remainder 1, and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 97 and 65 is 1
Notice that 1 = HCF(32,1) = HCF(65,32) = HCF(97,65) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 1, we apply the division lemma to 55 and 1, to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 55 is 1
Notice that 1 = HCF(55,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 118 > 1, we apply the division lemma to 118 and 1, to get
118 = 1 x 118 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 118 is 1
Notice that 1 = HCF(118,1) .
