HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 764, 204, 30 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 764, 204, 30 is 2 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 764, 204, 30 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 764, 204, 30 is 2.
HCF(764, 204, 30) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 764, 204, 30 is 2.
Step 1: Since 764 > 204, we apply the division lemma to 764 and 204, to get
764 = 204 x 3 + 152
Step 2: Since the reminder 204 ≠ 0, we apply division lemma to 152 and 204, to get
204 = 152 x 1 + 52
Step 3: We consider the new divisor 152 and the new remainder 52, and apply the division lemma to get
152 = 52 x 2 + 48
We consider the new divisor 52 and the new remainder 48,and apply the division lemma to get
52 = 48 x 1 + 4
We consider the new divisor 48 and the new remainder 4,and apply the division lemma to get
48 = 4 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 764 and 204 is 4
Notice that 4 = HCF(48,4) = HCF(52,48) = HCF(152,52) = HCF(204,152) = HCF(764,204) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 30 > 4, we apply the division lemma to 30 and 4, to get
30 = 4 x 7 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 30 is 2
Notice that 2 = HCF(4,2) = HCF(30,4) .
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 764, 204, 30?
Answer: HCF of 764, 204, 30 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 764, 204, 30 using Euclid's Algorithm?
Answer: For arbitrary numbers 764, 204, 30 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
