HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 381, 745, 551, 763 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 381, 745, 551, 763 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 381, 745, 551, 763 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 381, 745, 551, 763 is 1.
HCF(381, 745, 551, 763) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 381, 745, 551, 763 is 1.
Step 1: Since 745 > 381, we apply the division lemma to 745 and 381, to get
745 = 381 x 1 + 364
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 364 and 381, to get
381 = 364 x 1 + 17
Step 3: We consider the new divisor 364 and the new remainder 17, and apply the division lemma to get
364 = 17 x 21 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 381 and 745 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(364,17) = HCF(381,364) = HCF(745,381) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 551 > 1, we apply the division lemma to 551 and 1, to get
551 = 1 x 551 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 551 is 1
Notice that 1 = HCF(551,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 763 > 1, we apply the division lemma to 763 and 1, to get
763 = 1 x 763 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 763 is 1
Notice that 1 = HCF(763,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 381, 745, 551, 763?
Answer: HCF of 381, 745, 551, 763 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 381, 745, 551, 763 using Euclid's Algorithm?
Answer: For arbitrary numbers 381, 745, 551, 763 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
