HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 63, 854 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 63, 854 is 7 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 63, 854 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 63, 854 is 7.
HCF(63, 854) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 63, 854 is 7.
Step 1: Since 854 > 63, we apply the division lemma to 854 and 63, to get
854 = 63 x 13 + 35
Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 35 and 63, to get
63 = 35 x 1 + 28
Step 3: We consider the new divisor 35 and the new remainder 28, and apply the division lemma to get
35 = 28 x 1 + 7
We consider the new divisor 28 and the new remainder 7, and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 63 and 854 is 7
Notice that 7 = HCF(28,7) = HCF(35,28) = HCF(63,35) = HCF(854,63) .
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 63, 854?
Answer: HCF of 63, 854 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 63, 854 using Euclid's Algorithm?
Answer: For arbitrary numbers 63, 854 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
