HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 306, 866, 861, 297 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 306, 866, 861, 297 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 306, 866, 861, 297 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 306, 866, 861, 297 is 1.

HCF(306, 866, 861, 297) = 1

Highest Common Factor of 306,866,861,297 using Euclid's algorithm

Highest Common Factor of 306,866,861,297 is 1

Step 1: Since 866 > 306, we apply the division lemma to 866 and 306, to get

866 = 306 x 2 + 254

Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 254 and 306, to get

306 = 254 x 1 + 52

Step 3: We consider the new divisor 254 and the new remainder 52, and apply the division lemma to get

254 = 52 x 4 + 46

We consider the new divisor 52 and the new remainder 46,and apply the division lemma to get

52 = 46 x 1 + 6

We consider the new divisor 46 and the new remainder 6,and apply the division lemma to get

46 = 6 x 7 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 306 and 866 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(46,6) = HCF(52,46) = HCF(254,52) = HCF(306,254) = HCF(866,306) .


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

Step 1: Since 861 > 2, we apply the division lemma to 861 and 2, to get

861 = 2 x 430 + 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 861 is 1

Notice that 1 = HCF(2,1) = HCF(861,2) .


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

Step 1: Since 297 > 1, we apply the division lemma to 297 and 1, to get

297 = 1 x 297 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 297 is 1

Notice that 1 = HCF(297,1) .
