HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 7518 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 771, 7518 is 3 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 771, 7518 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 771, 7518 is 3.
HCF(771, 7518) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 771, 7518 is 3.
Step 1: Since 7518 > 771, we apply the division lemma to 7518 and 771, to get
7518 = 771 x 9 + 579
Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 579 and 771, to get
771 = 579 x 1 + 192
Step 3: We consider the new divisor 579 and the new remainder 192, and apply the division lemma to get
579 = 192 x 3 + 3
We consider the new divisor 192 and the new remainder 3, and apply the division lemma to get
192 = 3 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 771 and 7518 is 3
Notice that 3 = HCF(192,3) = HCF(579,192) = HCF(771,579) = HCF(7518,771) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 771, 7518?
Answer: HCF of 771, 7518 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 771, 7518 using Euclid's Algorithm?
Answer: For arbitrary numbers 771, 7518 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
