HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 266, 144, 549 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 266, 144, 549 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 266, 144, 549 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 266, 144, 549 is 1.

HCF(266, 144, 549) = 1

Highest common factor (HCF) of 266, 144, 549 is 1.

Highest Common Factor of 266,144,549 using Euclid's algorithm

Highest Common Factor of 266,144,549 is 1

Step 1: Since 266 > 144, we apply the division lemma to 266 and 144, to get

266 = 144 x 1 + 122

Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 122 and 144, to get

144 = 122 x 1 + 22

Step 3: We consider the new divisor 122 and the new remainder 22, and apply the division lemma to get

122 = 22 x 5 + 12

We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get

22 = 12 x 1 + 10

We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get

12 = 10 x 1 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 266 and 144 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(122,22) = HCF(144,122) = HCF(266,144) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 549 > 2, we apply the division lemma to 549 and 2, to get

549 = 2 x 274 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 549 is 1

Notice that 1 = HCF(2,1) = HCF(549,2) .
