HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 117, 527, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 117, 527, 12 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 117, 527, 12 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 117, 527, 12 is 1.
HCF(117, 527, 12) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 117, 527, 12 is 1.
Step 1: Since 527 > 117, we apply the division lemma to 527 and 117, to get
527 = 117 x 4 + 59
Step 2: Since the reminder 117 ≠ 0, we apply division lemma to 59 and 117, to get
117 = 59 x 1 + 58
Step 3: We consider the new divisor 59 and the new remainder 58, and apply the division lemma to get
59 = 58 x 1 + 1
We consider the new divisor 58 and the new remainder 1, and apply the division lemma to get
58 = 1 x 58 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 117 and 527 is 1
Notice that 1 = HCF(58,1) = HCF(59,58) = HCF(117,59) = HCF(527,117) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
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 117, 527, 12?
Answer: HCF of 117, 527, 12 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 117, 527, 12 using Euclid's Algorithm?
Answer: For arbitrary numbers 117, 527, 12 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
