HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 772 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 324, 772 is 4 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 324, 772 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 324, 772 is 4.
HCF(324, 772) = 4
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 324, 772 is 4.
Step 1: Since 772 > 324, we apply the division lemma to 772 and 324, to get
772 = 324 x 2 + 124
Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 124 and 324, to get
324 = 124 x 2 + 76
Step 3: We consider the new divisor 124 and the new remainder 76, and apply the division lemma to get
124 = 76 x 1 + 48
We consider the new divisor 76 and the new remainder 48,and apply the division lemma to get
76 = 48 x 1 + 28
We consider the new divisor 48 and the new remainder 28,and apply the division lemma to get
48 = 28 x 1 + 20
We consider the new divisor 28 and the new remainder 20,and apply the division lemma to get
28 = 20 x 1 + 8
We consider the new divisor 20 and the new remainder 8,and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 324 and 772 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(28,20) = HCF(48,28) = HCF(76,48) = HCF(124,76) = HCF(324,124) = HCF(772,324) .
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 324, 772?
Answer: HCF of 324, 772 is 4 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 324, 772 using Euclid's Algorithm?
Answer: For arbitrary numbers 324, 772 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
