HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 885 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 885 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 657, 885 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 657, 885 is 3.
HCF(657, 885) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 657, 885 is 3.
Step 1: Since 885 > 657, we apply the division lemma to 885 and 657, to get
885 = 657 x 1 + 228
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 228 and 657, to get
657 = 228 x 2 + 201
Step 3: We consider the new divisor 228 and the new remainder 201, and apply the division lemma to get
228 = 201 x 1 + 27
We consider the new divisor 201 and the new remainder 27,and apply the division lemma to get
201 = 27 x 7 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 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 657 and 885 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(201,27) = HCF(228,201) = HCF(657,228) = HCF(885,657) .
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 657, 885?
Answer: HCF of 657, 885 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 657, 885 using Euclid's Algorithm?
Answer: For arbitrary numbers 657, 885 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
