HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 252, 364, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 252, 364, 65 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 252, 364, 65 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 252, 364, 65 is 1.
HCF(252, 364, 65) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 252, 364, 65 is 1.
Step 1: Since 364 > 252, we apply the division lemma to 364 and 252, to get
364 = 252 x 1 + 112
Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 112 and 252, to get
252 = 112 x 2 + 28
Step 3: We consider the new divisor 112 and the new remainder 28, and apply the division lemma to get
112 = 28 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 252 and 364 is 28
Notice that 28 = HCF(112,28) = HCF(252,112) = HCF(364,252) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 28, we apply the division lemma to 65 and 28, to get
65 = 28 x 2 + 9
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 9 and 28, to get
28 = 9 x 3 + 1
Step 3: We consider the new divisor 9 and the new remainder 1, and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 28 and 65 is 1
Notice that 1 = HCF(9,1) = HCF(28,9) = HCF(65,28) .
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 252, 364, 65?
Answer: HCF of 252, 364, 65 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 252, 364, 65 using Euclid's Algorithm?
Answer: For arbitrary numbers 252, 364, 65 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
