HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 911, 812, 449, 48 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 911, 812, 449, 48 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 911, 812, 449, 48 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 911, 812, 449, 48 is 1.
HCF(911, 812, 449, 48) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 911, 812, 449, 48 is 1.
Step 1: Since 911 > 812, we apply the division lemma to 911 and 812, to get
911 = 812 x 1 + 99
Step 2: Since the reminder 812 ≠ 0, we apply division lemma to 99 and 812, to get
812 = 99 x 8 + 20
Step 3: We consider the new divisor 99 and the new remainder 20, and apply the division lemma to get
99 = 20 x 4 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 911 and 812 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(99,20) = HCF(812,99) = HCF(911,812) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 449 > 1, we apply the division lemma to 449 and 1, to get
449 = 1 x 449 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 449 is 1
Notice that 1 = HCF(449,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 1, we apply the division lemma to 48 and 1, to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 48 is 1
Notice that 1 = HCF(48,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 911, 812, 449, 48?
Answer: HCF of 911, 812, 449, 48 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 911, 812, 449, 48 using Euclid's Algorithm?
Answer: For arbitrary numbers 911, 812, 449, 48 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
