HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 720, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 720, 433 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 427, 720, 433 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 427, 720, 433 is 1.
HCF(427, 720, 433) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 720, 433 is 1.
Step 1: Since 720 > 427, we apply the division lemma to 720 and 427, to get
720 = 427 x 1 + 293
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 293 and 427, to get
427 = 293 x 1 + 134
Step 3: We consider the new divisor 293 and the new remainder 134, and apply the division lemma to get
293 = 134 x 2 + 25
We consider the new divisor 134 and the new remainder 25,and apply the division lemma to get
134 = 25 x 5 + 9
We consider the new divisor 25 and the new remainder 9,and apply the division lemma to get
25 = 9 x 2 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 427 and 720 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(25,9) = HCF(134,25) = HCF(293,134) = HCF(427,293) = HCF(720,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 433 > 1, we apply the division lemma to 433 and 1, to get
433 = 1 x 433 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 433 is 1
Notice that 1 = HCF(433,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 427, 720, 433?
Answer: HCF of 427, 720, 433 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 427, 720, 433 using Euclid's Algorithm?
Answer: For arbitrary numbers 427, 720, 433 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
