HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 202 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 202 is 1 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 561, 202 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 561, 202 is 1.
HCF(561, 202) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 202 is 1.
Step 1: Since 561 > 202, we apply the division lemma to 561 and 202, to get
561 = 202 x 2 + 157
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 157 and 202, to get
202 = 157 x 1 + 45
Step 3: We consider the new divisor 157 and the new remainder 45, and apply the division lemma to get
157 = 45 x 3 + 22
We consider the new divisor 45 and the new remainder 22,and apply the division lemma to get
45 = 22 x 2 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 561 and 202 is 1
Notice that 1 = HCF(22,1) = HCF(45,22) = HCF(157,45) = HCF(202,157) = HCF(561,202) .
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 561, 202?
Answer: HCF of 561, 202 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 561, 202 using Euclid's Algorithm?
Answer: For arbitrary numbers 561, 202 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
