HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 936, 834 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 936, 834 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 561, 936, 834 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, 936, 834 is 3.
HCF(561, 936, 834) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 936, 834 is 3.
Step 1: Since 936 > 561, we apply the division lemma to 936 and 561, to get
936 = 561 x 1 + 375
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 375 and 561, to get
561 = 375 x 1 + 186
Step 3: We consider the new divisor 375 and the new remainder 186, and apply the division lemma to get
375 = 186 x 2 + 3
We consider the new divisor 186 and the new remainder 3, and apply the division lemma to get
186 = 3 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 561 and 936 is 3
Notice that 3 = HCF(186,3) = HCF(375,186) = HCF(561,375) = HCF(936,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 834 > 3, we apply the division lemma to 834 and 3, to get
834 = 3 x 278 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 834 is 3
Notice that 3 = HCF(834,3) .
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, 936, 834?
Answer: HCF of 561, 936, 834 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 561, 936, 834 using Euclid's Algorithm?
Answer: For arbitrary numbers 561, 936, 834 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
