HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 4224 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 777, 4224 is 3 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 777, 4224 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 777, 4224 is 3.
HCF(777, 4224) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 777, 4224 is 3.
Step 1: Since 4224 > 777, we apply the division lemma to 4224 and 777, to get
4224 = 777 x 5 + 339
Step 2: Since the reminder 777 ≠ 0, we apply division lemma to 339 and 777, to get
777 = 339 x 2 + 99
Step 3: We consider the new divisor 339 and the new remainder 99, and apply the division lemma to get
339 = 99 x 3 + 42
We consider the new divisor 99 and the new remainder 42,and apply the division lemma to get
99 = 42 x 2 + 15
We consider the new divisor 42 and the new remainder 15,and apply the division lemma to get
42 = 15 x 2 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 777 and 4224 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(99,42) = HCF(339,99) = HCF(777,339) = HCF(4224,777) .
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 777, 4224?
Answer: HCF of 777, 4224 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 777, 4224 using Euclid's Algorithm?
Answer: For arbitrary numbers 777, 4224 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
