HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 761, 287, 792 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 761, 287, 792 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 761, 287, 792 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 761, 287, 792 is 1.
HCF(761, 287, 792) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 761, 287, 792 is 1.
Step 1: Since 761 > 287, we apply the division lemma to 761 and 287, to get
761 = 287 x 2 + 187
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 187 and 287, to get
287 = 187 x 1 + 100
Step 3: We consider the new divisor 187 and the new remainder 100, and apply the division lemma to get
187 = 100 x 1 + 87
We consider the new divisor 100 and the new remainder 87,and apply the division lemma to get
100 = 87 x 1 + 13
We consider the new divisor 87 and the new remainder 13,and apply the division lemma to get
87 = 13 x 6 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 761 and 287 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(87,13) = HCF(100,87) = HCF(187,100) = HCF(287,187) = HCF(761,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 792 > 1, we apply the division lemma to 792 and 1, to get
792 = 1 x 792 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 792 is 1
Notice that 1 = HCF(792,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 761, 287, 792?
Answer: HCF of 761, 287, 792 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 761, 287, 792 using Euclid's Algorithm?
Answer: For arbitrary numbers 761, 287, 792 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
