HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 533, 912, 39 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 533, 912, 39 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 533, 912, 39 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 533, 912, 39 is 1.
HCF(533, 912, 39) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 533, 912, 39 is 1.
Step 1: Since 912 > 533, we apply the division lemma to 912 and 533, to get
912 = 533 x 1 + 379
Step 2: Since the reminder 533 ≠ 0, we apply division lemma to 379 and 533, to get
533 = 379 x 1 + 154
Step 3: We consider the new divisor 379 and the new remainder 154, and apply the division lemma to get
379 = 154 x 2 + 71
We consider the new divisor 154 and the new remainder 71,and apply the division lemma to get
154 = 71 x 2 + 12
We consider the new divisor 71 and the new remainder 12,and apply the division lemma to get
71 = 12 x 5 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 533 and 912 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(71,12) = HCF(154,71) = HCF(379,154) = HCF(533,379) = HCF(912,533) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 39 > 1, we apply the division lemma to 39 and 1, to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 39 is 1
Notice that 1 = HCF(39,1) .
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 533, 912, 39?
Answer: HCF of 533, 912, 39 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 533, 912, 39 using Euclid's Algorithm?
Answer: For arbitrary numbers 533, 912, 39 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
