HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 748, 486, 634 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 748, 486, 634 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 748, 486, 634 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 748, 486, 634 is 2.
HCF(748, 486, 634) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 748, 486, 634 is 2.
Step 1: Since 748 > 486, we apply the division lemma to 748 and 486, to get
748 = 486 x 1 + 262
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 262 and 486, to get
486 = 262 x 1 + 224
Step 3: We consider the new divisor 262 and the new remainder 224, and apply the division lemma to get
262 = 224 x 1 + 38
We consider the new divisor 224 and the new remainder 38,and apply the division lemma to get
224 = 38 x 5 + 34
We consider the new divisor 38 and the new remainder 34,and apply the division lemma to get
38 = 34 x 1 + 4
We consider the new divisor 34 and the new remainder 4,and apply the division lemma to get
34 = 4 x 8 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 748 and 486 is 2
Notice that 2 = HCF(4,2) = HCF(34,4) = HCF(38,34) = HCF(224,38) = HCF(262,224) = HCF(486,262) = HCF(748,486) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 634 > 2, we apply the division lemma to 634 and 2, to get
634 = 2 x 317 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 634 is 2
Notice that 2 = HCF(634,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 748, 486, 634?
Answer: HCF of 748, 486, 634 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 748, 486, 634 using Euclid's Algorithm?
Answer: For arbitrary numbers 748, 486, 634 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
