HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 55, 561 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 55, 561 is 11 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 55, 561 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 55, 561 is 11.
HCF(55, 561) = 11
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 55, 561 is 11.
Step 1: Since 561 > 55, we apply the division lemma to 561 and 55, to get
561 = 55 x 10 + 11
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 11 and 55, to get
55 = 11 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 55 and 561 is 11
Notice that 11 = HCF(55,11) = HCF(561,55) .
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 55, 561?
Answer: HCF of 55, 561 is 11 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 55, 561 using Euclid's Algorithm?
Answer: For arbitrary numbers 55, 561 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
