HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 416, 938, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 416, 938, 395 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 416, 938, 395 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 416, 938, 395 is 1.
HCF(416, 938, 395) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 416, 938, 395 is 1.
Step 1: Since 938 > 416, we apply the division lemma to 938 and 416, to get
938 = 416 x 2 + 106
Step 2: Since the reminder 416 ≠ 0, we apply division lemma to 106 and 416, to get
416 = 106 x 3 + 98
Step 3: We consider the new divisor 106 and the new remainder 98, and apply the division lemma to get
106 = 98 x 1 + 8
We consider the new divisor 98 and the new remainder 8,and apply the division lemma to get
98 = 8 x 12 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 416 and 938 is 2
Notice that 2 = HCF(8,2) = HCF(98,8) = HCF(106,98) = HCF(416,106) = HCF(938,416) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 2, we apply the division lemma to 395 and 2, to get
395 = 2 x 197 + 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 395 is 1
Notice that 1 = HCF(2,1) = HCF(395,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 416, 938, 395?
Answer: HCF of 416, 938, 395 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 416, 938, 395 using Euclid's Algorithm?
Answer: For arbitrary numbers 416, 938, 395 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
