HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 962, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 746, 962, 485 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 746, 962, 485 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 746, 962, 485 is 1.
HCF(746, 962, 485) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 746, 962, 485 is 1.
Step 1: Since 962 > 746, we apply the division lemma to 962 and 746, to get
962 = 746 x 1 + 216
Step 2: Since the reminder 746 ≠ 0, we apply division lemma to 216 and 746, to get
746 = 216 x 3 + 98
Step 3: We consider the new divisor 216 and the new remainder 98, and apply the division lemma to get
216 = 98 x 2 + 20
We consider the new divisor 98 and the new remainder 20,and apply the division lemma to get
98 = 20 x 4 + 18
We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get
20 = 18 x 1 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 746 and 962 is 2
Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(98,20) = HCF(216,98) = HCF(746,216) = HCF(962,746) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 2, we apply the division lemma to 485 and 2, to get
485 = 2 x 242 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 485 is 1
Notice that 1 = HCF(2,1) = HCF(485,2) .
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 746, 962, 485?
Answer: HCF of 746, 962, 485 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 746, 962, 485 using Euclid's Algorithm?
Answer: For arbitrary numbers 746, 962, 485 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
