HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 683, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 683, 455 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 949, 683, 455 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 949, 683, 455 is 1.
HCF(949, 683, 455) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 949, 683, 455 is 1.
Step 1: Since 949 > 683, we apply the division lemma to 949 and 683, to get
949 = 683 x 1 + 266
Step 2: Since the reminder 683 ≠ 0, we apply division lemma to 266 and 683, to get
683 = 266 x 2 + 151
Step 3: We consider the new divisor 266 and the new remainder 151, and apply the division lemma to get
266 = 151 x 1 + 115
We consider the new divisor 151 and the new remainder 115,and apply the division lemma to get
151 = 115 x 1 + 36
We consider the new divisor 115 and the new remainder 36,and apply the division lemma to get
115 = 36 x 3 + 7
We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get
36 = 7 x 5 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 683 is 1
Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(115,36) = HCF(151,115) = HCF(266,151) = HCF(683,266) = HCF(949,683) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get
455 = 1 x 455 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1
Notice that 1 = HCF(455,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 949, 683, 455?
Answer: HCF of 949, 683, 455 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 949, 683, 455 using Euclid's Algorithm?
Answer: For arbitrary numbers 949, 683, 455 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
