HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 273, 499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 273, 499 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 778, 273, 499 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 778, 273, 499 is 1.

HCF(778, 273, 499) = 1

Highest common factor (HCF) of 778, 273, 499 is 1.

Highest Common Factor of 778,273,499 using Euclid's algorithm

Highest Common Factor of 778,273,499 is 1

Step 1: Since 778 > 273, we apply the division lemma to 778 and 273, to get

778 = 273 x 2 + 232

Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 232 and 273, to get

273 = 232 x 1 + 41

Step 3: We consider the new divisor 232 and the new remainder 41, and apply the division lemma to get

232 = 41 x 5 + 27

We consider the new divisor 41 and the new remainder 27,and apply the division lemma to get

41 = 27 x 1 + 14

We consider the new divisor 27 and the new remainder 14,and apply the division lemma to get

27 = 14 x 1 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 778 and 273 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(41,27) = HCF(232,41) = HCF(273,232) = HCF(778,273) .

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

Step 1: Since 499 > 1, we apply the division lemma to 499 and 1, to get

499 = 1 x 499 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 499 is 1

Notice that 1 = HCF(499,1) .
