HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 759, 308 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 993, 759, 308 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 993, 759, 308 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 993, 759, 308 is 1.
HCF(993, 759, 308) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 993, 759, 308 is 1.
Step 1: Since 993 > 759, we apply the division lemma to 993 and 759, to get
993 = 759 x 1 + 234
Step 2: Since the reminder 759 ≠ 0, we apply division lemma to 234 and 759, to get
759 = 234 x 3 + 57
Step 3: We consider the new divisor 234 and the new remainder 57, and apply the division lemma to get
234 = 57 x 4 + 6
We consider the new divisor 57 and the new remainder 6,and apply the division lemma to get
57 = 6 x 9 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 993 and 759 is 3
Notice that 3 = HCF(6,3) = HCF(57,6) = HCF(234,57) = HCF(759,234) = HCF(993,759) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 308 > 3, we apply the division lemma to 308 and 3, to get
308 = 3 x 102 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 308 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(308,3) .
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 993, 759, 308?
Answer: HCF of 993, 759, 308 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 993, 759, 308 using Euclid's Algorithm?
Answer: For arbitrary numbers 993, 759, 308 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
