HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 511, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 511, 654 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 782, 511, 654 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 782, 511, 654 is 1.
HCF(782, 511, 654) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 511, 654 is 1.
Step 1: Since 782 > 511, we apply the division lemma to 782 and 511, to get
782 = 511 x 1 + 271
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 271 and 511, to get
511 = 271 x 1 + 240
Step 3: We consider the new divisor 271 and the new remainder 240, and apply the division lemma to get
271 = 240 x 1 + 31
We consider the new divisor 240 and the new remainder 31,and apply the division lemma to get
240 = 31 x 7 + 23
We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 782 and 511 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(240,31) = HCF(271,240) = HCF(511,271) = HCF(782,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get
654 = 1 x 654 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1
Notice that 1 = HCF(654,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 782, 511, 654?
Answer: HCF of 782, 511, 654 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 782, 511, 654 using Euclid's Algorithm?
Answer: For arbitrary numbers 782, 511, 654 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
