HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 277, 499, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 277, 499, 77 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 277, 499, 77 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 277, 499, 77 is 1.

HCF(277, 499, 77) = 1

HCF of 277, 499, 77 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 277, 499, 77 is 1.

Highest Common Factor of 277,499,77 using Euclid's algorithm

Highest Common Factor of 277,499,77 is 1

Step 1: Since 499 > 277, we apply the division lemma to 499 and 277, to get

499 = 277 x 1 + 222

Step 2: Since the reminder 277 ≠ 0, we apply division lemma to 222 and 277, to get

277 = 222 x 1 + 55

Step 3: We consider the new divisor 222 and the new remainder 55, and apply the division lemma to get

222 = 55 x 4 + 2

We consider the new divisor 55 and the new remainder 2,and apply the division lemma to get

55 = 2 x 27 + 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 277 and 499 is 1

Notice that 1 = HCF(2,1) = HCF(55,2) = HCF(222,55) = HCF(277,222) = HCF(499,277) .


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

Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get

77 = 1 x 77 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1

Notice that 1 = HCF(77,1) .
