HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 307, 273 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 777, 307, 273 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 777, 307, 273 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 777, 307, 273 is 1.

HCF(777, 307, 273) = 1

Highest common factor (HCF) of 777, 307, 273 is 1.

Highest Common Factor of 777,307,273 using Euclid's algorithm

Highest Common Factor of 777,307,273 is 1

Step 1: Since 777 > 307, we apply the division lemma to 777 and 307, to get

777 = 307 x 2 + 163

Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 163 and 307, to get

307 = 163 x 1 + 144

Step 3: We consider the new divisor 163 and the new remainder 144, and apply the division lemma to get

163 = 144 x 1 + 19

We consider the new divisor 144 and the new remainder 19,and apply the division lemma to get

144 = 19 x 7 + 11

We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get

19 = 11 x 1 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 777 and 307 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(144,19) = HCF(163,144) = HCF(307,163) = HCF(777,307) .

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

Step 1: Since 273 > 1, we apply the division lemma to 273 and 1, to get

273 = 1 x 273 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 273 is 1

Notice that 1 = HCF(273,1) .
