HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 626, 266, 27 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 626, 266, 27 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 247, 626, 266, 27 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 247, 626, 266, 27 is 1.

HCF(247, 626, 266, 27) = 1

Highest Common Factor of 247,626,266,27 using Euclid's algorithm

Highest Common Factor of 247,626,266,27 is 1

Step 1: Since 626 > 247, we apply the division lemma to 626 and 247, to get

626 = 247 x 2 + 132

Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 132 and 247, to get

247 = 132 x 1 + 115

Step 3: We consider the new divisor 132 and the new remainder 115, and apply the division lemma to get

132 = 115 x 1 + 17

We consider the new divisor 115 and the new remainder 17,and apply the division lemma to get

115 = 17 x 6 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 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 247 and 626 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(115,17) = HCF(132,115) = HCF(247,132) = HCF(626,247) .

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

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

266 = 1 x 266 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 266 is 1

Notice that 1 = HCF(266,1) .

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

Step 1: Since 27 > 1, we apply the division lemma to 27 and 1, to get

27 = 1 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 27 is 1

Notice that 1 = HCF(27,1) .
