HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 624, 666, 289 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 624, 666, 289 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 624, 666, 289 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 624, 666, 289 is 1.
HCF(624, 666, 289) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 624, 666, 289 is 1.
Step 1: Since 666 > 624, we apply the division lemma to 666 and 624, to get
666 = 624 x 1 + 42
Step 2: Since the reminder 624 ≠ 0, we apply division lemma to 42 and 624, to get
624 = 42 x 14 + 36
Step 3: We consider the new divisor 42 and the new remainder 36, and apply the division lemma to get
42 = 36 x 1 + 6
We consider the new divisor 36 and the new remainder 6, and apply the division lemma to get
36 = 6 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 624 and 666 is 6
Notice that 6 = HCF(36,6) = HCF(42,36) = HCF(624,42) = HCF(666,624) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 289 > 6, we apply the division lemma to 289 and 6, to get
289 = 6 x 48 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 289 is 1
Notice that 1 = HCF(6,1) = HCF(289,6) .
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 624, 666, 289?
Answer: HCF of 624, 666, 289 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 624, 666, 289 using Euclid's Algorithm?
Answer: For arbitrary numbers 624, 666, 289 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
