HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 772, 793 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 505, 772, 793 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 505, 772, 793 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 505, 772, 793 is 1.

HCF(505, 772, 793) = 1

Highest common factor (HCF) of 505, 772, 793 is 1.

Highest Common Factor of 505,772,793 using Euclid's algorithm

Highest Common Factor of 505,772,793 is 1

Step 1: Since 772 > 505, we apply the division lemma to 772 and 505, to get

772 = 505 x 1 + 267

Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 267 and 505, to get

505 = 267 x 1 + 238

Step 3: We consider the new divisor 267 and the new remainder 238, and apply the division lemma to get

267 = 238 x 1 + 29

We consider the new divisor 238 and the new remainder 29,and apply the division lemma to get

238 = 29 x 8 + 6

We consider the new divisor 29 and the new remainder 6,and apply the division lemma to get

29 = 6 x 4 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 505 and 772 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(29,6) = HCF(238,29) = HCF(267,238) = HCF(505,267) = HCF(772,505) .

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

Step 1: Since 793 > 1, we apply the division lemma to 793 and 1, to get

793 = 1 x 793 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 793 is 1

Notice that 1 = HCF(793,1) .
