HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 677, 920 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 677, 920 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 938, 677, 920 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 938, 677, 920 is 1.
HCF(938, 677, 920) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 938, 677, 920 is 1.
Step 1: Since 938 > 677, we apply the division lemma to 938 and 677, to get
938 = 677 x 1 + 261
Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 261 and 677, to get
677 = 261 x 2 + 155
Step 3: We consider the new divisor 261 and the new remainder 155, and apply the division lemma to get
261 = 155 x 1 + 106
We consider the new divisor 155 and the new remainder 106,and apply the division lemma to get
155 = 106 x 1 + 49
We consider the new divisor 106 and the new remainder 49,and apply the division lemma to get
106 = 49 x 2 + 8
We consider the new divisor 49 and the new remainder 8,and apply the division lemma to get
49 = 8 x 6 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 938 and 677 is 1
Notice that 1 = HCF(8,1) = HCF(49,8) = HCF(106,49) = HCF(155,106) = HCF(261,155) = HCF(677,261) = HCF(938,677) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 920 > 1, we apply the division lemma to 920 and 1, to get
920 = 1 x 920 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 920 is 1
Notice that 1 = HCF(920,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 938, 677, 920?
Answer: HCF of 938, 677, 920 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 938, 677, 920 using Euclid's Algorithm?
Answer: For arbitrary numbers 938, 677, 920 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
