HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 775, 298, 257 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 775, 298, 257 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 775, 298, 257 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 775, 298, 257 is 1.

HCF(775, 298, 257) = 1

HCF of 775, 298, 257 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 775, 298, 257 is 1.

Highest Common Factor of 775,298,257 using Euclid's algorithm

Highest Common Factor of 775,298,257 is 1

Step 1: Since 775 > 298, we apply the division lemma to 775 and 298, to get

775 = 298 x 2 + 179

Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 179 and 298, to get

298 = 179 x 1 + 119

Step 3: We consider the new divisor 179 and the new remainder 119, and apply the division lemma to get

179 = 119 x 1 + 60

We consider the new divisor 119 and the new remainder 60,and apply the division lemma to get

119 = 60 x 1 + 59

We consider the new divisor 60 and the new remainder 59,and apply the division lemma to get

60 = 59 x 1 + 1

We consider the new divisor 59 and the new remainder 1,and apply the division lemma to get

59 = 1 x 59 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 775 and 298 is 1

Notice that 1 = HCF(59,1) = HCF(60,59) = HCF(119,60) = HCF(179,119) = HCF(298,179) = HCF(775,298) .


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

Step 1: Since 257 > 1, we apply the division lemma to 257 and 1, to get

257 = 1 x 257 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 257 is 1

Notice that 1 = HCF(257,1) .
