HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 96, 55, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 96, 55, 70 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 96, 55, 70 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 96, 55, 70 is 1.
HCF(96, 55, 70) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 96, 55, 70 is 1.
Step 1: Since 96 > 55, we apply the division lemma to 96 and 55, to get
96 = 55 x 1 + 41
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 41 and 55, to get
55 = 41 x 1 + 14
Step 3: We consider the new divisor 41 and the new remainder 14, and apply the division lemma to get
41 = 14 x 2 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 96 and 55 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(41,14) = HCF(55,41) = HCF(96,55) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get
70 = 1 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1
Notice that 1 = HCF(70,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 96, 55, 70?
Answer: HCF of 96, 55, 70 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 96, 55, 70 using Euclid's Algorithm?
Answer: For arbitrary numbers 96, 55, 70 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
