HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 546, 690, 281 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 546, 690, 281 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 546, 690, 281 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 546, 690, 281 is 1.
HCF(546, 690, 281) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 546, 690, 281 is 1.
Step 1: Since 690 > 546, we apply the division lemma to 690 and 546, to get
690 = 546 x 1 + 144
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 144 and 546, to get
546 = 144 x 3 + 114
Step 3: We consider the new divisor 144 and the new remainder 114, and apply the division lemma to get
144 = 114 x 1 + 30
We consider the new divisor 114 and the new remainder 30,and apply the division lemma to get
114 = 30 x 3 + 24
We consider the new divisor 30 and the new remainder 24,and apply the division lemma to get
30 = 24 x 1 + 6
We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get
24 = 6 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 546 and 690 is 6
Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(114,30) = HCF(144,114) = HCF(546,144) = HCF(690,546) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 281 > 6, we apply the division lemma to 281 and 6, to get
281 = 6 x 46 + 5
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get
6 = 5 x 1 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 281 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(281,6) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 546, 690, 281?
Answer: HCF of 546, 690, 281 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 546, 690, 281 using Euclid's Algorithm?
