HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 664, 268 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 664, 268 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 742, 664, 268 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 742, 664, 268 is 2.
HCF(742, 664, 268) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 664, 268 is 2.
Step 1: Since 742 > 664, we apply the division lemma to 742 and 664, to get
742 = 664 x 1 + 78
Step 2: Since the reminder 664 ≠ 0, we apply division lemma to 78 and 664, to get
664 = 78 x 8 + 40
Step 3: We consider the new divisor 78 and the new remainder 40, and apply the division lemma to get
78 = 40 x 1 + 38
We consider the new divisor 40 and the new remainder 38,and apply the division lemma to get
40 = 38 x 1 + 2
We consider the new divisor 38 and the new remainder 2,and apply the division lemma to get
38 = 2 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 742 and 664 is 2
Notice that 2 = HCF(38,2) = HCF(40,38) = HCF(78,40) = HCF(664,78) = HCF(742,664) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 268 > 2, we apply the division lemma to 268 and 2, to get
268 = 2 x 134 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 268 is 2
Notice that 2 = HCF(268,2) .
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 742, 664, 268?
Answer: HCF of 742, 664, 268 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 742, 664, 268 using Euclid's Algorithm?
Answer: For arbitrary numbers 742, 664, 268 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
